Ralf, in your example the popup shell is created only once in the constructor. Closing the shell will dispose it. The second time when you try to open the shell again, it is already disposed. To workaround this, create a new shell if it is disposed. In current CVS HEAD (1.3M3) we introduced WidgetDisposed check - see bug 263048. Your snippet throws exception (org.eclipse.swt.SWTException: Widget is disposed) in this case. Thanks a lot. I think this solves the problem. I didn't see any exception and therefore didn't know where to search for errors. After resolving Bug 263048 this Bug can be closed. Since Bug 263048 was resolved this Bug can be marked as resolved, too. |
Created attachment 151278 [details] Project file for test I made a simple HelloWorld Plugin which only displays a simple View. Then I created a class which displays a text field and a button. If you press the button, a new list field opens and you can select one ore more values. On focus lost the selected values are copied into the text field. The first time this works correct. But if you press the button for the second time, the following error message appears: Could not evaluate javascript response: 'w' ist Null oder kein Objekt org.eclipse.swt.EventUtil.suspendEventHandling();var req = org.eclipse.swt.Request.getInstance();req.setRequestCounter( "10" );var wm = org.eclipse.swt.WidgetManager.getInstance();var w = wm.findWidgetById( "w5" );w.setSpace( 254, 112, -90, 110 );w.setActive( true );var w = wm.newWidget( "w55", "w5", true, null, "org.eclipse.swt.widgets.List" );w.init( true );w.addState( "rwt_BORDER" );w.setOverflow( "auto" );w.setSpace( 0, 0, 0, 0 );w.setZIndex( 300 );w.setTabIndex( 1 );w.addEventListener( "focusin", org.eclipse.swt.EventUtil.focusGained );w.addEventListener( "focusout", org.eclipse.swt.EventUtil.focusLost );w.setItems( [ "Broccoli", "Bundt Cake", "Cabbage", "Candy Canes", "Eggs", "Potato Chips", "Milk", "Soda", "Chicken", "Cinnamon Rolls" ] );w.selectItems( [1,2,3 ] );w.focusItem( 1 );w.setChangeSelectionNotification( "action" );var w = wm.findWidgetById( "w5" );w.setActiveControl( wm.findWidgetById( "w55" ) );org.eclipse.swt.WidgetManager.getInstance().focus( "w55" );qx.ui.core.Widget.flushGlobalQueues();org.eclipse.swt.EventUtil.resumeEventHandling(); Perhaps I used something in the wrong way. The version of RAP with which I've tested is 1.2.0 and 1.2.1. Please see the attached project file.
