Build Identifier: 3.4.2 M20090211-1700 If you build a cheat sheet, in which an item has a command to call another cheat sheet my example <command required="false" serialization="org.eclipse.ui.cheatsheets.openCheatSheet(cheatSheetId=com.castsoftware.pmc.intro.createdeliveryunit)"/> When the user fires that command, he gets a SWTException saying that a widget is disposed. I could see in the debugguer this widget is a LayoutComposite, but I cannot tell where it comes from. There is no problem if the user switches cheat sheets himself using the menu and the cheat sheet panel (note: removing the parameter in my example, having then the command show the cheat sheets panel, does not remove the bug) Reproducible: Always Steps to Reproduce: 1.create 2 cheat sheets 2. in one of them, add a command to call the other 3. run that cheat sheet, then run that command
What's the stack trace of the SWTException? If it's not in the console, check the logs - <workspace>/.metadata/.log PW
Here is the stack trace: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:3777) at org.eclipse.swt.SWT.error(SWT.java:3695) at org.eclipse.swt.SWT.error(SWT.java:3666) at org.eclipse.swt.widgets.Widget.error(Widget.java:463) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:336) at org.eclipse.swt.widgets.Composite.getChildren(Composite.java:410) at org.eclipse.ui.internal.cheatsheets.views.CoreItem.getStartButton(CoreItem.java:284) at org.eclipse.ui.internal.cheatsheets.views.CoreItem.setRestartImage(CoreItem.java:557) at org.eclipse.ui.internal.cheatsheets.views.CheatSheetViewer.runPerformExecutable(CheatSheetViewer.java:1046) at org.eclipse.ui.internal.cheatsheets.views.CoreItem$1.linkActivated(CoreItem.java:89) at org.eclipse.ui.forms.widgets.AbstractHyperlink.handleActivate(AbstractHyperlink.java:228) at org.eclipse.ui.forms.widgets.ImageHyperlink.handleActivate(ImageHyperlink.java:177) at org.eclipse.ui.forms.widgets.AbstractHyperlink.handleMouseUp(AbstractHyperlink.java:322) at org.eclipse.ui.forms.widgets.AbstractHyperlink.access$2(AbstractHyperlink.java:306) at org.eclipse.ui.forms.widgets.AbstractHyperlink$4.handleEvent(AbstractHyperlink.java:120) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2384) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2348) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2200) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:495) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:490) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at com.castsoftware.pmc.workbench.Application$WorkbenchPMCConfiguredApplication.onGUIRun(Application.java:115) at com.castsoftware.mda.run.ConfiguredApplication.run(ConfiguredApplication.java:70) at com.castsoftware.pmc.workbench.Application.start(Application.java:36) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) 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:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) at org.eclipse.equinox.launcher.Main.main(Main.java:1212)
Thanx. Maybe switching to another cheatsheet is causing some of the processing in runPerformExecutable(CheatSheetViewer.java:1046) to run against a disposed composite? Moving to UA for comments. PW
I can take a look at this.
This was fixed in Eclipse 3.6 - see Bug 291750 for a patch. *** This bug has been marked as a duplicate of bug 291750 ***
