This bug relates to Eclipse Classic 4.3 Developer release M7. It appeared in a previous pre-release, disappeared in M6, but now re-appears again. When invoking the consetext sensitive help in a Java program the help window appears within the workspace. Then I detach the help window to a separate window frame. When I close Eclipse now and open it again, the complete window settin (workspace window and separate help window) appears again. When the help window is closed and then Eclipse is closed and opened again, the workspace window shows the "Plug-in Development" perspective rather than the "Java" perspective.
Cannot reproduce this with eclipse-classic-kepler-M7-win32 , nor with eclipse-SDK-4.3RC1-win32. I can't imagine that the Eclipse EPP package contributes anything beyond the original Eclipse SDK which would trigger this. Please try to reproduce with the original eclipse-SDK-4.3RC1 : http://download.eclipse.org/eclipse/downloads/drops4/S-4.3RC1-201305162200/ If you can reproduce the case, reopen the bug and provide as exact steps.
Created attachment 231298 [details] Screenshots Attached screenshots (sent by private E-Mail) illustrate the problem. Compared to the original steps to reproduce, Screen4.png shows that the user had navigated to the Java online docs in the detached help window. Screen6.png and Screen8.png show several exceptions in the errorlog ("Unable to load resource file" and others). Some exceptions point to remnants of WindowBuilder (org.eclipse.wb). It looks like the same workspace had been in use with the Eclipse Java package before. When opening the same workspace with Eclipse Classic/SDK later, some references to WindowBuilder are broken (actionset), because WindowBuilder is not part of Classic/SDK. I assume that the unexpected switching from the Java perspective to the PDE perspective is due to one of the exceptions in the log. Please attach the log file such that we can see whether any further investigation makes sense. Also, please try to reproduce with Classic/SDK on a fresh empty workspace (I assume you won't be able to reproduce). Thanks, Martin
You find the log as a file in the workspace (C:\workspace\.metadata\.log) Or, in the errorlog view, press the “Export” button. Or, Help > About > Installations Details : Configuration Tab : View Errorlog button , then save.
I reproduced the problem with Eclipse Platform SDK 4.3M7. I could not reproduce it with Eclipse 4.3RC1. I assume that the problem has been fixed for RC1 - reassigning to Platform / UI for duplicating to the proper bug fix. Steps to reproduce with Platform SDK 4.3M7: ------------------------------------------- 1. Launch SDK on a fresh empty workspace 2. In Welcome page, choose SWT Examples and have them installed 3. New > Other > Code Samples > SWT 4. Open "Plug-In Development" perspective 5. Open "Debug" perspective 6. Close "Java" Perspective 7. Switch to "Plug In Development" perspective, close the Welcome view 8. Expan o.e.swt.examples.paint, dbl click PainView to load in the editor 9. Select "ViewPart", F1 open context help 10. Drag Context Help View out of the IDE to make a separate window 11. In the detached help window navigate to "IViewPart" then to "IWorkbenchPart" 12. Quite Eclipse and restart --> Help View reappears detached, PDE perspective is still active 13. Close detached help window 14. Quit and restart Workbench --> Workbench comes up in the default "Java" perspective, perspective layout is all destroyed --> Errorlog view has attached, this is the key exception: !MESSAGE Unable to load resource file:/D:/Eclipse/eclipse4.3m7/workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi !STACK 0 org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.e4.ui.model.application.ui.basic.impl.PartStackImpl@83020 (elementId: stickyFolderRight, tags: null, contributorURI: null) (widget: null, renderer: null, toBeRendered: false, onTop: false, visible: true, containerData: 2500, accessibilityPhrase: null)' is not legal.
