Scout 6.0 Migration Guide

This document describes the migration from Scout 5.0 to Scout 6.0

Project Structure

With the upgrade to pure maven without OSGi the project structure should be changed to the maven default [1]:

Listing 1. Eclipse Plugin Structure (Scout 5.0, old)
org.eclipsescout.helloworld.client
    pom.xml
    plugin.xml
    src
        org
            eclipsescout
                helloworld
                    ClientSession.java
                    Activator.java

org.eclipsescout.helloworld.test
    pom.xml
    plugin.xml
    src
        org
            eclipsescout
                helloworld
                    HelloworldTest.java
Listing 2. Maven Project Structure (Scout 6.0, new)
org.eclipsescout.helloworld.client
    pom.xml
    src
        main
            java
                org
                    eclipsescout
                        helloworld
                            ClientSession.java
        test
            java
                org
                    eclipsescout
                        helloworld
                            HelloworldTest.java

Manifest.MF

Manifest.MF is no longer used. Migrate dependencies to pom.xml!

AccessControlService

The IAccessControlService has been improved to allow for other keys than the userId. AbstractAccessControlService is now generic with key as a type parameter.

If you want to use access control based on the userid as before, extend UserIdAccessControlService and change the API of execLoadPermissions to

protected abstract PermissionCollection execLoadPermissions(String userId)

IShellService

The ShellService can no longer be used because there is no access to the client side shell. Instead you can use the following code to send a document to clients:

BinaryResource binaryResource = new BinaryResource(templateFile.getName(), myRawData);
ClientSessionProvider.currentSession().getDesktop()
  .openUri(binaryResource, OpenUriAction.DOWNLOAD);

Desktop

  • Renamed IDesktop.openUrlInBrowser to openUri, since passed String is not always an URL but sometimes an URI like tel:123 or mailto:foo@bar.com, etc.

  • Renamed IDesktop.openDownloadInBrowser to downloadResource, added overridden methods with BinaryResource parameter, so it’s not required to create a IDownloadHandler instance to use the download methods.

  • Renamed IUrlTarget to ITargetWindows, UrlTarget to TargetWindow

  • Renamed DesktopEvent.TYPE_OPEN_URL_IN_BROWSER to TYPE_OPEN_URI

  • Renamed DesktopEvent.TYPE_OPEN_DOWNLOAD_IN_BROWSER to TYPE_DOWNLOAD_RESOURCE

  • F5 Keystroke on the desktop to reload the current page is no longer necessary because the table itself now provides the f5 keystroke → Remove the keystroke from your desktop to prevent refreshing the table twice.

Offline

Offline functionality in the scout client was removed (not needed anymore). Delete - OfflineState - IClientSession.getOfflineSubject - IDesktop.changeVisibilityAfterOfflineSwitch

All owners of an IContextMenu now share a common interface: IContextMenuOwner. This interface provides a method getMenuByClass(T), analogous to getFieldByClass(T), getColumnByClass(T) etc.

ITree and ITable provided a similar method getMenu(T). This method was deprecated in favor of getMenuByClass(T).

Usually, the migration is completed by simply renaming all calls to the old method. However, it should be noted that the old behavior is not exactly reproduced in a special case: When more than one implementation of the given class T was found, the old method just returned the first instance found. The new method throws an exception in this case, because the order of the instances is not really defined. If you really want to find any instance of the given class, retrieve the list of all instances using getMenus() and apply the filtering by yourself.

The constructors of OutlineMenuWrapper changed. For details consult the javadoc. This was needed to ensure the correct menuTypes throughout the wrapped menu’s sub-hierarchy.

The CopyColumnsWidthsMenu has been deleted and was replaced with a new button in OrganizeColumnsForm.

Message Box

  • Removed title. No replacement, title is not supported anymore.

  • renamed intro text to header & info/actionText to body.

  • using method chaining to construct message box

    • getHiddenText() → getHiddenText()

    • setHiddenText(hiddenText) → withHiddenText(hiddenText) and returning instance of IMessageBox

  • Renamed startMessageBox to show

  • Removed MessageBox(String title, String introText, String okButtonText) → MessageBoxes.create().withHeader(introText).withYesButtonText(okButtonText)

  • Removed MessageBox(String title, String introText, String actionText, String yesButtonText, String noButtonText, String cancelButtonText) → MessageBoxes.create().withHeader(introText).withBody(actionText) .withYesButtonText(yesButtonText).withNoButtonText(noButtonText).cancelButtonText(cancelButtonText);

  • Removed MessageBox(String title, String introText, String actionText, String yesButtonText, String noButtonText, String cancelButtonText, String hiddenText, String iconId) → MessageBoxes.create().withHeader(introText) .withBody(actionText).withYesButtonText(yesButtonText).withNoButtonText(noButtonText).withCancelButtonText(cancelButtonText).withHiddenText(hiddenText).withIconId(iconId);

  • Moved MessageBox.showDeleteConfirmationMessage methods to MessagesBoxes class

  • If html needs to be displayed, use the new html(IHtmlContent) method. Header / body methods do not support html.

Table

Table API Changes

  • Renamed ITable.resetDisplayableColumns() to resetColumns()

  • Removed ITable.resetColumns(boolean, boolean, boolean, boolean) from interface (is now protected in AbstractTable)

  • AbstractTable.execResetTable(…​): changed signature

    • old: protected void execResetColumns(boolean visibility, boolean order, boolean sorting, boolean widths)

    • new: protected void execResetColumns(Set<String> options)

  • Changed signature of ClientUIPreferences.getTableCustomizerData

    • From ClientUIPreferences.getTableCustomizerData(String customizerKey) to ClientUIPreferences.getTableCustomizerData(ITableCustomizer customizer, String configName)

    • From ClientUIPreferences.setTableCustomizerData(String customizerKey, Object customizerData) to ClientUIPreferences.setTableCustomizerData(ITableCustomizer customizer, String configName)

  • Replaced ITableColumnFilterManager by TableUserFilterManager

    Reason for the rename is because more filter types were added. There are currently 2 filter types: Column filter and text filter, there will be a chart filter in the future. Additionally, the filtering now happens in the UI. The ui sends the filtered rows to the ui server to update its table state so that getFilteredRows return the currently visible rows on the ui. This rowsFiltered event leads to a creation of UserTableRowFilter which contains the filtered rows. This is the only active filter on a table. The filters managed by TableUserFilterManager are actually only filter states and are not added to the table.

  • AbstractColumn.execPrepareEdit(ITableRow) must not return null anymore use Cell.setEditable(boolean) instead.

  • Added ITable#rowIconVisible to control whether the row icon is visible or not. If set to true the gui creates a column which contains the row icons. The column has a fixed width, is not moveable and always the first column (resp. the second if the table is checkable). The column is not available in the model.

    If you need other settings or if you need the icon at another column position, you cannot use the row icons. Instead you have to create a column and use Cell#setIconId(String) to set the icons on it’s cells.

    If you used ITableRow#setIconId or AbstractTable#getConfiguredDefaultIconId and still want the icons to be visible, you have to set getConfiguredRowIconVisible to true.

  • Refactored editable behaviour of cells.

    • Table.isCellEditable only returns cell.editable and does not consider table or row enabled and visible states. Conforms to the behaviour of the other cell properties (text, cssStyle, etc).

    • execIsEditable has been removed. Use cell.setEditable (e.g. in execDecorateCell) if you want a cell to behave differently than the column.

    • decorateCellInternal does not write properties to the cell anymore, this is now done initially or if the column property changes. Advantage: It’s now possible to modify the cell properties outside of execDecorateCell. Furthermore, there is no need to execute this code so many times.

    • Removed ICell.setEnabled. Did not have any effect, use row.setEnabled instead. Or ICell.setEditable if you would like to control editability of a cell.

  • InternalTableRow / AbstractTable: checked state of a row is moved to the table. The TYPE_ROWS_UPDATED is no longer used to notify about rows checked. Instead there is an event TYPE_ROWS_CHECKED which is fired when rows are checked or unchecked. Also there is a new Method on the model which is executed when rows are checked (execRowsChecked). This method is also available in extensions.

    A row should be set to checked from the model even if the row is disabled. For this, the method setRowsChecked is extended with a new parameter to identify if only enabled rows should be checked or not. The ui should only check enabled rows, so the ui-facade calls the method with true.

Custom Table Sorting

Added IColumn.uiSortPossible

Sorting of table data is done by the ui whenever possible. This has the advantage, that it is faster, that less data is transferred and that it works in offline mode. The drawback is that it is not possible in every case.

Example: If an invisible column has alwaysSortAtBegin set to true, the sorting is delegated to the model. Furthermore smart columns can not be sorted by the ui because the value is not known.

If you implemented custom sorting (e.g. by overriding AbstractColumn.compareTableRows), you have to set getConfiguredUiSortPossible to false.

Table Field & Page

  • Removed "populate status" and "selection status" methods from IPage and ITableField. The only status is on the table itself and is called "table status". IPage and ITableField have new convenience methods for getting/setting the table status (without requiring null checks on getTable()).

    Migration:

    • Replace IPage.setPagePopulateStatus() by IPage.setTableStatus().

    • Replace IPage.getPagePopulateStatus() by IPage.getTableStatus().

    • Properties PROP_TABLE_SELECTION_STATUS, PROP_TABLE_POPULATE_STATUS, PROP_TABLE_STATUS_VISIBLE no longer exist on ITableField. If you need to listen to them, change your listener target the the field’s ITable.

    • Method ITableField.createDefaultTableStatus() was dropped without replacement. "Selection status" is not supported by Html UI at the moment (selection is visualized on the UI only, not in the model).

    • ITableField.get/setTableStatus() convenience methods with Strings were dropped without replacement. Use ITableField.getTableStatus().get/setMessage() instead.

    • ITableField.get/setTableSelectionStatus() were dropped without replacement. "Selection status" is not supported by Html UI at the moment (selection is visualized on the UI only, not in the model).

    • Change ITableField.get/setTablePopulateStatus() to ITableField.get/setTableStatus()

    • ITableField.updateTableStatus() was dropped without replacement. Simply set the table status with ITableField.setTableStatus().

    • getConfiguredTableStatusVisible() was dropped without replacement. Instead, the initial "table status visible" property should be set on the table. (In most cases, you can simply move the getConfiguredTableStatusVisible() method from the table field to the table.

  • Removed AbstractPageWithTable.getConfiguredShowTableRowMenus. Replacement: none (no functionality was provided).

  • Removed AbstractPageWithTable.getConfiguredShowEmptySpaceMenus Replacement: if return value was false, override computeTableEmptySpaceMenus and return an empty list instead.

  • API of IPageWithTable and IPageWithNodes merged and moved duplicate methods to IPage

    • IPage now has a T getTable() method, also changed abstract classes implementing these interfaces. IPage now expects a type parameter for the table.

    • API IPage:

      • added T getTable()

      • added boolean isDetailFormVisible()

      • added void setDetailFormVisible(boolean visible)

      • added ITreeNode getTreeNodeFor(ITableRow tableRow)

      • added IPage getPageFor(ITableRow tableRow)

      • added ITableRow getTableRowFor(ITreeNode treeNode)

      • added List<ITableRow> getTableRowsFor(Collection<? extends ITreeNode> treeNodes)

    • API IPageWithNodes:

      • getInternalTable() replaced by getTable

      • moved to IPage: ITreeNode getTreeNodeFor(ITableRow tableRow)

      • moved to IPage: ITableRow getTableRowFor(ITreeNode childPageNode)

    • API IPageWithTable:

      • moved to IPage: T getTable()

      • moved to IPage: ITreeNode getTreeNodeFor(ITableRow tableRow)

      • moved to IPage: ITableRow getTableRowFor(ITreeNode childPageNode)

      • moved to IPage: List<ITableRow> getTableRowsFor(Collection<? extends ITreeNode> childPageNodes)

  • Improved page detail form handling: The detail form is now created and started when the page gets activated and closed when the page gets disposed, similar to the search form. API added getConfiguredDetailForm, execInitDetailForm, createDetailForm, startDetailForm.

    Remove the detail form handling code from execPageActivated / execPageDeactivated / execPageDisposed and use either getConfiguredDetailForm / execInitDetailForm or createDetailForm.

Outline

  • Removed IOutlineTableForm, IOutlineTreeForm and all sub-classes. They’re not supported by the new Html UI anymore.

Default Page selection of Outlines

For an Outline having a selected page is not mandatory anymore. An outline overview or the default detail form will be displayed if no page is selected. Therefore activating an outline does not automatically select the first page anymore.

If the previous behavior is still wanted, one can implemented IDesktop.execOutlineChanged and call activateFirstPage if active page is null.

Wizard

  • Argument containerForm was removed. Use getContainerForm() instead.

  • Method decorateWizardContainerForm was renamed to execDecorateContainerForm (same as execCreateContainerForm).

    Old code (MyWizard extends AbstractWizard):

  @Override
  protected IWizardContainerForm execCreateContainerForm() {
    MyWizardContainerForm containerForm = new MyWizardContainerForm(this);
    decorateWizardContainerForm(containerForm);
    // more custom modifications
    return containerForm;
  }

New code:

  @Override
  protected IWizardContainerForm execCreateContainerForm() {
    return new MyWizardContainerForm(this);
  }

  @Override
  protected void execDecorateContainerForm() {
    getContainerForm().setXyz(...);
    // more custom modifications
  }
  • Some properties were removed from IWizard:

    • displayHint, displayViewId, modal -→ no replacement. Set them on the wizard container form. If the wizard container form does not provide the correct value, the wizard may change them in execDecorateContainerForm().

    • iconId, tooltipText, wizardNo -→ no replacement (legacy properties, never used).

    • titleHtml: use subTitle instead.

  • getWizard[…​]Button() methods in IWizardContainerForm no longer return IButton, but IWizardAction. This change allows returning menus instead of buttons. IWizardAction serves as a common interface for IButton and IAction and provides some methods that are commonly used for the wizard buttons (e.g. setVisible, setEnabled). Because IAction calls its label "text", those menus have to override getLabel/setLabel and delegate the calls to the corresponding "text" methods. Alternatively, the class AbstractWizardMenu may be used instead of AbstractMenu.

    • For own implementations of IWizardContainerForm, replace the return value IButton by IWizardAction.

    • For code that previously used the setView(boolean, boolean, boolean) method on wizard buttons, a new setView(boolean, boolean) method was introduced on IButton and IAction (because it does not make sense to make a button "mandatory"). This can be migrated by just deleting the third argument.

Form

  • get/setBasicTitle removed

  • get/setSubTitle added

  • PROP_SUB_TITLE added

  • composeTitle removed.

  • Added default behaviour to AbstractForm.execCreateFormData The method now creates a new instance of the form data based on the form data annotation. Also added createFormData to the IForm interface. If execCreateFormData was implemented and just used the default constructor of the corresponding form data class, the method may be removed.

  • Removed display-hint IForm.DISPLAY_HINT_POPUP_DIALOG. Not supported anymore. Use dialog or popup-window instead.

Form Fields

  • Deleted AbstractCheckBox, AbstractCheckboxExtension, ICheckBoxExtension, ICheckBox.

    Use AbstractBooleanField, AbstractBooleanExtension, IBooleanExtension, IBooleanField instead.

  • Renamed package imagebox to imagefield due to consistency reason.

  • Deprecated getConfiguredAutoDisplayText in AbstractValueField. The display text is always updated automatically.

  • Removed AbstractDoubleField and AbstractDoubleColumn. Use AbstractBigDecimalField and AbstractBigDecimalColumn instead. See Bug 464770.

  • Renamed package org.eclipse.scout.rt.client.ui.form.fields.colorpicker to .colorfield.

  • Removed ContributedKeyStroke method from all FormField classes because these are only the menus which are added on the field. Use getMenus() instead.

  • All AbstractExtensible* Scout elements have been deleted. Use the normal element instead (e.g. use AbstractStringField instead of AbstractExtensibleStringField). For extension support use the corresponding extension object (e.g. AbstractStringFieldExtension).

  • Deleted IMailField, AbstractMailField and all associated classes and files.

    An application that requires a facility to compose an e-mail should create a form with the fields required for that application (Multiline-StringField for plain-text E-Mails, RichTextField for HTML e-mails, FileChooserField for file uploads, etc.)

  • Deleted ICustomField/AbstractCustomField and all associated classes and files.

  • Deleted IDocumentField/AbstractDocumentField and all associated classes and files.

  • getConfiguredTreat0AsNull in Smartfield has been deleted. (see also Bugzilla 469902).

  • Changed return value of IGroupBox.getConfiguredScrollable to TriState. Mainbox is now scrollable by default.

    Migration:

    • You can remove getConfiguredScrollable() from your mainboxes

    • If you want another groupbox to be scrollable, you have to set the groupbox to scrollable while setting the mainbox to scrollable = false.

  • Removed IToolButton from forms. Therefore IToolButtons can not be added anymore as an extension to forms. Instead IToolButton can be defined inside the MainBox of a form. (IToolButton now is an IMenu and adding menus to GroupBoxes as extension is also supported.)

  • Simplified form tool buttons: Refactored API to be consistent with detail and search form handling of a page. Remove the form handling code from execStartForm and use either getConfiguredForm / execInitForm or createForm.

  • The search table control now gets selected if the search is required. If you had a SearchFormToolButton, remove the code in Desktop.execPageSearchFormChanged.

  • When setting an inner form into an WrappedFormField using setInnerForm(IForm) the given form life cycle is handled by the wrapped form field. This means it is automatically started, disposed etc.

Validate on any Key

Replace ValidateOnAnyKey mechanism (getConfiguredValidateOnAnyKey) (Bug 459893):

  • removed:

    • IBasicField.setValidateOnAnyKey(boolean)

    • IBasicField.isValidateOnAnyKey()

    • IBasicField.PROP_VALIDATE_ON_ANY_KEY

  • use new updateDisplayTextOnModify-mechanism instead:

    • IBasicField.setUpdateDisplayTextOnModify(boolean)

    • IBasicField.isUpdateDisplayTextOnModify(boolean)

    • AbstractBasicField.execChangedDisplayText()

    • IBasicField.PROP_UPDATE_DISPLAY_TEXT_ON_MODIFY

  • IBasicFieldUIFacade renamed and changed method:

    • from: boolean setTextFromUI(String newText, boolean whileTyping)

    • to: void setValueFromUI(String value)

  • removed IColorFieldUiFacade

String Field

  • Deleted AbstractTextField, AbstractTextFieldExtension, ITextFieldExtension, ITextField`.

    Use AbstractStringField, AbstractStringExtension, IStringExtension, IStringField instead.

  • Method renaming: getConfiguredDecorationLink()getConfiguredHasAction().

  • Method renaming: isDecorationLink()isHasAction().

  • Method renaming: setDecorationLink(boolean)setHasAction(boolean).

  • Method renaming/signature change: execLinkAction(java.net.URL)execAction(). execAction() can access value using getValue(), it could create the old URL using org.eclipse.scout.commons.IOUtility.urlTextToUrl(getValue()).

  • Removed IStringField.isSpellCheckAsYouTypeEnabled(), IStringField.setSpellCheckAsYouTypeEnabled(boolean) added IStringField.setSpellCheckEnabled(boolean) new ui delegates spell checker to browser, new property can be used to enable/disable spell checker for certain fields (by default it is enabled for multi-line fields, see AbstractStringField.computeSpellCheckEnabled()).

  • Removed IStringField.isSelectAllOnFocus(), IStringField.setSelectAllOnFocus(boolean), IStringColumn.isSelectAllOnEdit(), IStringColumn.setSelectAllOnEdit(boolean).

Browser Field

  • IBrowserField is no longer a value field. The RemoteFile value was changed to a property of type BinaryResource.

    • Instead of setValue()/getValue() use setBinaryResource()/getBinaryResource().

    • Instead of execChangedValue() use a BrowserFieldListener.

    • If you relied on the browser field to be "save needed" when setting the value (RemoteFile), you have to call touch() manually, because the browser field will never report "save needed" by itself (because it has no value).

  • removed AbstractBrowserField.execAcceptLocationChange, AbstractBrowserField.execLocationChanged, AbstractBrowserField.doLocationChange. Use AbstractBrowserField.execPostMessage as replacement.

  • Refactored execHyperlinkAction. With the new html ui real hyperlinks are handled by the browser. Other links (formerly local links) are now called app links. The new method execAppLinkAction is only called for app links, hence the parameters url and local are not necessary anymore.

    • Removed parameter url and local and renamed path to ref.

    • Renamed to execAppLinkAction

Date Field

  • Removed the members m_autoDate and m_autoTimeMillis from AbstractDateField. They were replaced by a single property PROP_AUTO_DATE of type java.util.Date.

    Replace getConfiguredAutoTimeMillis()/setAutoTimeMillis()/getAutoTimeMillis() by getConfiguredAutoDate()/setAutoDate()/getAutoDate(). If both a date and time part should be set, combine them in the same java.util.Date argument. The methods DateUtility.createDateTime() and DateUtility.convertDoubleTimeToDate() may be useful.

  • The UI facade of AbstractDateField was changed. To support offline, more responsive date/time validation on the new Html UI, formatting and parsing has to be performed on the UI layer, not on the model layer (otherwise, the UI would have to wait for the model on every key press).

    The date field UI facade was changed in the following way: Instead of sending a text to the model and validating/parsing it there, a already valid (from the parsing perspective) date is sent to the model. The model may then still validate it (e.g. check ranges), but the parsing is done entirely on the UI. As a consequence, not all date format patterns defined in SimpleDateFormat are supported anymore, only the most commonly used. By default, the date field uses locale-dependent patterns that are supported by the UI, see getDefaultDateFormatPatternByLocale() and getDefaultTimeFormatPatternByLocale(). Both the date and the time part of a date field have a separate pattern, because they are rendered in two separate fields on the UI.

    The method AbstractDateField.execParseValue() is no longer supported. It cannot be removed entirely, because it is defined on AbstractValueField, but is marked as deprecated and final to make it clear that it is never called. If any subclass had overridden this method, it should be deleted. The code cannot be migrated, because it is now performed in the UI only.

  • Removed methods not used by the HTML UI: + remove unused execShiftDate, execShiftTime from AbstractDateField + remove unused adjustDate, adjustTime from IDateField + removed fireDateShiftActionFromUI, fireTimeShiftActionFromUI from IDateFieldUIFacade

HTML Field

  • For IHtmlField attachments RemoteFile has been replaced by BinaryResource, therefore method signatures of getAttachments() and setAttachments have changed.

    • Replace RemoteFile with BinaryResource.

    • Attachments must be used within the IHtmlField’s value as `src="binaryResource:test.png" (instead of src="test.png"). Append binaryResource: prefix where attachments are used.

    • New feature: Icons can be used without adding them as attachment using src="iconid:ApplicationLogo".

    • New property for selection tracking, changeable with methods isSelectionTrackingEnabled() and setSelectionTrackingEnabled(boolean). Selection tracking with getSelectionStart() and getSelectionEnd() is only possible when selection tracking is enabled.

  • Removed html editor support on html field. If you used a html editor you can create a custom field an include an existing html editor.

Tree, TreeField & TreeBox

  • If all child nodes of a node in a tree are deleted, a TreeEvent with the new type ALL_CHILD_NODES_DELETED is fired (instead of NODES_DELETED). This is useful for optimization.

    If you previously added a listener for the type NODES_DELETED, you have to check if your implementation needs to listen to the new ALL_CHILD_NODES_DELETED as well.

  • AbstractTreeNode / AbstractTree / AbstractTreeBox: checked state of a row is moved to the tree. The TYPE_NODE_UPDATED is no longer used to notify about node checked. Instead there is an event TYPE_NODES_CHECKED which is fired when nodes are checked or unchecked. Also there is a new Method on the model which is executed when nodes are checked (execNodessChecked). This method is also available in extensions.

    Also the implementation to check child nodes of a tree when a parent is checked is moved from the AbstractTreeBox to the tree. But the configuration can be done on the AbstractTreeBox. A node should be set to checked from the model even if the node is disabled. For this, the method setNodesChecked is extended with a new param to identify if only enabled nodes should be checked or not. The ui should only check enabled nodes, so the ui-facade calls the method with true.

Calendar, CalendarField, Planner

  • Moved display-mode constants from ICalender and IPlanner to separate interface classes and let IPlannerDisplayMode extend ICalenderDisplayMode because they share some constants.

  • Removed get/setColor() from ICalenderItem, replaced with get/setCssClass().

  • Removed decorateCell/-Internal method from AbstractCalendarItemProvider

  • Moved get/setExternalKey() from ICalendarAppointment to base class ICalenderItem.

  • Removed cell instance from CalendarComponent

Utilities

  • Removed methods UserAgentUtility.isRichClient() and .isWebClient().

  • HTMLUtility has been deprecated. There is no replacement.

  • NumberUtility.sum(double…​) -→ use sum(Number…​)

  • NumberUtility.sum(long…​) -→ use sum(Number…​)

  • Removed NumberUtility.avg(double…​)

  • Removed NumberUtility.divide(double, double)

  • The following Classes have been moved. Organize imports to fix errors:

    • IDNDSupport

    • TransferObject

    • TextTransferObject

    • ResourceListTransferObject

    • JavaTransferObject

    • ImageTransferObject

    • All Classes that once existed in org.eclipse.scout.commons.*. Most of them have been moved to org.eclipse.scout.rt.platform.*.

  • Renamed FileListTransferObject to ResourceListTransferObject

  • Removed isText(), isFileList(), isImage(), isLocalObject() from TransferObject. Replacement: instanceof check for the appropriate subclasses of TransferObject.

  • Removed TextTransferObject(String plainText, String htmlText) and TextTransferObject.getHtmlText(). See Bug 465797.

  • Moved MultiClientSessionCookieStore to org.eclipse.scout.rt.servicetunnel and renamed it to MultiSessionCookieStore. It can now be used in client and server environments.

    To make the service tunnel work with multiple sessions over HTTP, the MultiSessionCookieStore has to be installed. This is not done automatically, because the cookie manager is global for the entire JVM. Overriding this global variable may break things in a JEE environment with multiple applications or a pre-installed custom cookie manager. There are two options to install Scout’s MultiSessionCookieStore:

    • Set the default cookie manager programmatically somewhere in your code. This is the way provided by the JVM, see http://docs.oracle.com/javase/tutorial/networking/cookies/cookiemanager.html for details.

    • Use Scout’s auto-install mechanism by setting the property org.eclipse.scout.rt.servicetunnel.multiSessionCookieStoreEnabled in your config.properties to true. This is the recommended way.

Cryptography

EncryptionUtility, PublicKeyUtility, TripleDES have been deprecated because these classes use insecure cryptography. Use the new SecurityUtility or the Java Cryptography Architecture instead [2].

When changing the cryptography algorithms in you application please keep in mind that all existing encrypted, hashed or signed data becomes invalid! Consider migrating these data first.

Various API Changes

  • Changed ILookupRow to fluent API: use with…​ instead of set…​

  • IClientSession.stopSession() was renamed to stop() to match IServerSession.stop().

  • Deleted validation rule infrastructure: Deleted package org.eclipse.scout.rt.shared.validate with all subpackages and the containing classes. Furthermore the class org.eclipse.scout.rt.shared.data.form.ValidationRule has been deleted.

Logging API

Scout switched from a custom, typically java.util.logging-based logger implementation to SLF4j. The log format does not support indexed placeholders anymore.

The regular expression pattern \{\d+\} finds potential occurrences. Replace those within log formats with {}. See SLF4j MessageFormatter.

Listing 3. Placeholders in log format
LOG.info("message {}", obj); // this worked before and still works. No action required

LOG.info("message {0}", obj); // the index is not supported anymore. You have to remove it (see previous statement)
Indexed placeholders are actually deprecated since Scout’s open-source debut. The values were filled in from left to right, independent of the possibly declared index.

Logging configuration

migrate logging.properties to logback.xml

1) in logging.properties apply the following regex replacements:

search: ^(\w.*)\.level\s*=\s*(ALL|OFF|SEVERE|WARNING|INFO|FINE|FINEST)\s*$
replace: <logger name="$1" level="$2"/>

search: ^(\w.*)\.useParentHandlers\s*=\s*(false)\s*$
replace: <logger name="$1"><appender-ref ref="CONSOLE"/></logger>

search: ^#+\s*(.*)$
replace: <!-- $1 -->

search: (FINEST|finest)
replace: TRACE

search: (FINE|fine)
replace: DEBUG

search: (WARNING|warning)
replace: WARN

search: (SEVERE|severe)
replace: ERROR

2) create a new logback.xml as

<?xml version="1.0" encoding="UTF-8" ?>

Migrate to the new Job API

Eclipse jobs are replaced by Scout Job Manager API.

In a nutshell

Scout provides a job manager based on Java Executors framework to run tasks in parallel, and on Quartz Trigger API to support for schedule plans. A task (aka job) can be scheduled to commence execution either immediately upon being scheduled, or delayed some time in the future. A job can be single executing, or recurring based on some schedule plan.

A job is defined as some work to be executed asynchronously and is associated with a JobInput to describe how to run that work. The work is given to the job manager in the form of a Runnable or Callable. The only difference is, that a Runnable represents a 'fire-and-forget' action, meaning that the submitter of the job does not expect the job to return a result. On the other hand, a Callable returns the computation’s result, which the submitter can await for. Of course, a runnable’s completion can also be waited for.

See Scout architecture documentation for more information.

Static accessors

  • ServerJob.getCurrentSession() → ServerSessionProvider.currentSession()

  • ClientJob.getCurrentSession() → ClientSessionProvider.currentSession()

  • ServerJob.isCurrentJobCancelled() → RunMonitor.CURRENT.get().isCancelled()

Raw Eclipse Job

Listing 4. before Scout 'N' release (<=5.0.x)
new Job("job-name") {

  @Override
  protected IStatus run(IProgressMonitor monitor) {
    // do something
  }
}.schedule();
Listing 5. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withName("job-name"));

ServerJob

Listing 6. before Scout 'N' release (<=5.0.x)
new ServerJob("job-name", ServerJob.getCurrentSession()) {

  @Override
  protected IStatus runTransaction(IProgressMonitor monitor) throws Exception {
    // do something
    return Status.OK_STATUS;
  }
}.schedule();
Listing 7. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withRunContext(ServerRunContexts.copyCurrent())
    .withName("job-name"));

ServerJob.runNow(…​)

Listing 8. before Scout 'N' release (<=5.0.x)
new ServerJob("job-name", ServerJob.getCurrentSession()) {

  @Override
  protected IStatus runTransaction(IProgressMonitor monitor) throws Exception {
    // do something
    return Status.OK_STATUS;
  }
}.runNow(new NullProgressMonitor());
Listing 9. since Scout 'N' release (>=5.1.x)
ServerRunContexts.copyCurrent().run(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
});

ServerJob with other Subject

Listing 10. before Scout 'N' release (<=5.0.x)
new ServerJob("job-name", ServerJob.getCurrentSession(), subject) {

  @Override
  protected IStatus runTransaction(IProgressMonitor monitor) throws Exception {
    // do something
    return Status.OK_STATUS;
  }
}.schedule();
Listing 11. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withName("job-name")
    .withRunContext(ServerRunContexts.copyCurrent()
        .withSubject(subject)));

ClientSyncJob

Listing 12. before Scout 'N' release (<=5.0.x)
new ClientSyncJob("job-name", ClientSessionProvider.currentSession()) {

  @Override
  protected void runVoid(IProgressMonitor monitor) throws Throwable {
    // do something
  }
}.schedule();
Listing 13. since Scout 'N' release (>=5.1.x)
ModelJobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, ModelJobs
    .newInput(ClientRunContexts.copyCurrent())
    .withName("job-name"));

ClientAsyncJob

Listing 14. before Scout 'N' release (<=5.0.x)
new ClientAsyncJob("job-name", ClientSessionProvider.currentSession()) {

  @Override
  protected void runVoid(IProgressMonitor monitor) throws Throwable {
    // do something
  }
}.schedule();
Listing 15. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withRunContext(ClientRunContexts.copyCurrent())
    .withName("job-name"));

Delayed execution

Listing 16. before Scout 'N' release (<=5.0.x)
new Job("job-name") {

  @Override
  protected IStatus run(IProgressMonitor monitor) {
    // do something
  }
}.schedule(5_000);
Listing 17. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withName("job-name")
    .withExecutionTrigger(Jobs.newExecutionTrigger()
        .withStartIn(5, TimeUnit.SECONDS)));

Repeatedly execution with a fixed delay

Listing 18. before Scout 'N' release (<=5.0.x)
new Job("job-name") {

  @Override
  protected IStatus run(IProgressMonitor monitor) {
    // do something
    schedule(5_000);
  }
}.schedule(5_000);
Listing 19. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do something
  }
}, Jobs.newInput()
    .withName("job-name")
    .withExecutionTrigger(Jobs.newExecutionTrigger()
        .withSchedule(FixedDelayScheduleBuilder.repeatForever(5, TimeUnit.SECONDS))
        .withStartIn(5, TimeUnit.SECONDS)));

Check for cancellation

Listing 20. before Scout 'N' release (<=5.0.x)
new Job("job-name") {

  @Override
  protected IStatus run(IProgressMonitor monitor) {
    // do first chunk of work
    if (monitor.isCanceled()) {
        return Status.CANCEL_STATUS;
    }
    // do second chunk of work
    if (monitor.isCanceled()) {
      return Status.CANCEL_STATUS;
    }
    // do third chunk of work
    return Status.OK_STATUS;
  }
}.schedule();
Listing 21. since Scout 'N' release (>=5.1.x)
Jobs.schedule(new IRunnable() {

  @Override
  public void run() throws Exception {
    // do first chunk of work
    if (RunMonitor.CURRENT.get().isCancelled()) {
      return;
    }
    // do second chunk of work
    if (RunMonitor.CURRENT.get().isCancelled()) {
      return;
    }
    // do third chunk of work
  }
}, Jobs.newInput()
    .withName("job-name"));

Join job

Job job = new Job("job-name") {

  @Override
  protected IStatus run(IProgressMonitor monitor) {
    // do something
    result.set("abc");
    return Status.OK_STATUS;
  }

job.join();
System.out.println(result);
Listing 27. since Scout 'N' release (>=5.1.x)
IFuture<String> future = Jobs.schedule(new Callable<String>() {

  @Override
  public String call() throws Exception {
    // do something
