Using Eclipse 3.2/M6 Sorry for just posting a stack trace, I realize that this is not optimal, but I do not know specifics under which this happened. org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:3374) at org.eclipse.swt.SWT.error(SWT.java:3297) at org.eclipse.swt.SWT.error(SWT.java:3268) at org.eclipse.swt.widgets.Widget.error(Widget.java:432) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:327) at org.eclipse.swt.widgets.Widget.getData(Widget.java:485) at org.eclipse.ui.part.MultiPageEditorPart.getEditor(MultiPageEditorPart.java:417) at org.eclipse.ui.part.MultiPageEditorPart.removePage(MultiPageEditorPart.java:644) at org.eclipse.ui.forms.editor.FormEditor.removePage(FormEditor.java:359) at org.eclipse.pde.internal.ui.editor.plugin.ManifestEditor.updateFirstThreePages(ManifestEditor.java:314) at org.eclipse.pde.internal.ui.editor.plugin.ManifestEditor.contextAdded(ManifestEditor.java:300) at org.eclipse.pde.internal.ui.editor.context.InputContextManager.fireContextChange(InputContextManager.java:244) at org.eclipse.pde.internal.ui.editor.plugin.PluginInputContextManager.fireContextChange(PluginInputContextManager.java:55) at org.eclipse.pde.internal.ui.editor.context.InputContextManager.putContext(InputContextManager.java:126) at org.eclipse.pde.internal.ui.editor.plugin.ManifestEditor.monitoredFileAdded(ManifestEditor.java:221) at org.eclipse.pde.internal.ui.editor.context.InputContextManager.fireStructureChange(InputContextManager.java:235) at org.eclipse.pde.internal.ui.editor.context.InputContextManager.structureChanged(InputContextManager.java:206) at org.eclipse.pde.internal.ui.editor.context.InputContextManager.access$1(InputContextManager.java:200) at org.eclipse.pde.internal.ui.editor.context.InputContextManager$2.run(InputContextManager.java:195) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3323) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2969) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1914) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1878) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:419) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:95) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:78) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:92) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:68) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:376) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:169) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:336) at org.eclipse.core.launcher.Main.basicRun(Main.java:280) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952)
This is a legitimate call to remove an existent page from the manifest editor. Moving to platform/ui where the code is failing. FYI, it appears as though this happened when the user had a 3.0 style plugin (ie. no manifest.mf) and pressed the link in the Content section of the Overview page of the editor to 'Create an OSGi bundle manifest).
Simon, were there any other errors in the log? This happens a lot when another action fails part way through. PW
Hm, I've not seen this one since moving to RC1, so perhaps it was exactly that, a side effect of some other gremlins. Maybe we can close this for now.
Is this still a problem in 3.3? PW
I have not seen this recently.
Oh, this is a dup of another bug that PDE recently fixed. PW
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
