1. Open the 'Properties' view. 2. Open an XSD file. 3. Switch to the 'Source' view. 4. A CCE is thrown. From the code a downcast to StructuredSelection is made directly from ISelection. This seems wrong but doesn't occur on 3.x for whatever reasons. Will need to cross-check what's going on on that side. java.lang.ClassCastException: org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider$StructuredTextSelection at org.eclipse.wst.xsd.ui.internal.editor.XSDTabbedPropertySheetPage.selectionChanged(XSDTabbedPropertySheetPage.java:49) at org.eclipse.ui.views.properties.PropertySheet.selectionChanged(PropertySheet.java:365) at org.eclipse.ui.internal.e4.compatibility.SelectionService.notifyListeners(SelectionService.java:158) at org.eclipse.ui.internal.e4.compatibility.SelectionService.access$3(SelectionService.java:156) at org.eclipse.ui.internal.e4.compatibility.SelectionService$1.selectionChanged(SelectionService.java:72) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl.notifyListeners(SelectionServiceImpl.java:196) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl.access$4(SelectionServiceImpl.java:191) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl$2.changed(SelectionServiceImpl.java:234) at org.eclipse.e4.core.internal.contexts.TrackableComputationExt.update(TrackableComputationExt.java:91) at org.eclipse.e4.core.internal.contexts.EclipseContext.processScheduled(EclipseContext.java:326) at org.eclipse.e4.core.internal.contexts.EclipseContext.set(EclipseContext.java:343) at org.eclipse.e4.ui.internal.workbench.SelectionServiceImpl.setSelection(SelectionServiceImpl.java:251) at org.eclipse.ui.internal.e4.compatibility.SelectionService.selectionChanged(SelectionService.java:314) at org.eclipse.ui.part.MultiPageSelectionProvider$1.run(MultiPageSelectionProvider.java:110) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.part.MultiPageSelectionProvider.fireEventChange(MultiPageSelectionProvider.java:108) at org.eclipse.ui.part.MultiPageSelectionProvider.firePostSelectionChanged(MultiPageSelectionProvider.java:102) at org.eclipse.ui.part.MultiPageEditorSite.handlePostSelectionChanged(MultiPageEditorSite.java:440) at org.eclipse.ui.part.MultiPageEditorSite$3.selectionChanged(MultiPageEditorSite.java:352) at org.eclipse.wst.sse.ui.StructuredTextEditor$4.run(StructuredTextEditor.java:592) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider.fireSelectionChanged(StructuredTextEditor.java:590) at org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider.handlePostSelectionChanged(StructuredTextEditor.java:671) at org.eclipse.wst.sse.ui.StructuredTextEditor$3.selectionChanged(StructuredTextEditor.java:564) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2746) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2694) at org.eclipse.jface.text.TextViewer$5.run(TextViewer.java:2673) at org.eclipse.swt.widgets.Display.runTimer(Display.java:4227) at org.eclipse.swt.widgets.Display.messageProc(Display.java:3314) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2524) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3713)
Actually, the problem occurred while I was using 3.x inner with minimal dependencies. java.lang.ClassCastException: org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider$StructuredTextSelection at org.eclipse.wst.xsd.ui.internal.editor.XSDTabbedPropertySheetPage.selectionChanged(XSDTabbedPropertySheetPage.java:49) at org.eclipse.ui.views.properties.PropertySheet.selectionChanged(PropertySheet.java:365) at org.eclipse.ui.internal.AbstractSelectionService.firePostSelection(AbstractSelectionService.java:179) at org.eclipse.ui.internal.AbstractSelectionService$2.selectionChanged(AbstractSelectionService.java:71) at org.eclipse.ui.part.MultiPageSelectionProvider$1.run(MultiPageSelectionProvider.java:110) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.part.MultiPageSelectionProvider.fireEventChange(MultiPageSelectionProvider.java:108) at org.eclipse.ui.part.MultiPageSelectionProvider.firePostSelectionChanged(MultiPageSelectionProvider.java:102) at org.eclipse.ui.part.MultiPageEditorSite.handlePostSelectionChanged(MultiPageEditorSite.java:428) at org.eclipse.ui.part.MultiPageEditorSite$3.selectionChanged(MultiPageEditorSite.java:340) at org.eclipse.wst.sse.ui.StructuredTextEditor$4.run(StructuredTextEditor.java:592) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider.fireSelectionChanged(StructuredTextEditor.java:590) at org.eclipse.wst.sse.ui.StructuredTextEditor$StructuredSelectionProvider.handlePostSelectionChanged(StructuredTextEditor.java:671) at org.eclipse.wst.sse.ui.StructuredTextEditor$3.selectionChanged(StructuredTextEditor.java:564) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2746) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2694) at org.eclipse.jface.text.TextViewer$5.run(TextViewer.java:2673)
Fixed in HEAD.
(In reply to comment #2) > Fixed in HEAD. Nitin, this bug is still open. Is there more work to be done?
Depends on whether XSD wants to fix it in 3.2.4. Keith?
Hi Nitin, yes, please fix it for 3.2.4.
Released to 3.2.4.
