Build Identifier: M20100909-0800 When I click on "Run Configuration..." I get the following: Undefined context while filtering dialog/window contexts: org.eclipse.core.commands.common.NotDefinedException: Cannot get the parent identifier from an undefined context. org.eclipse.ui.externaltools.ExternalToolsSet at org.eclipse.core.commands.contexts.Context.getParentId(Context.java:201) at org.eclipse.jface.bindings.BindingManager.createFilteredContextTreeFor(BindingManager.java:825) at org.eclipse.jface.bindings.BindingManager.recomputeBindings(BindingManager.java:1721) at org.eclipse.jface.bindings.BindingManager.getActiveBindings(BindingManager.java:921) at org.eclipse.jface.bindings.BindingManager.isPerfectMatch(BindingManager.java:1625) at org.eclipse.jface.action.ExternalActionManager$CommandCallback.isAcceleratorInUse(ExternalActionManager.java:347) at org.eclipse.jface.action.MenuManager.update(MenuManager.java:898) at org.eclipse.jface.action.MenuManager.update(MenuManager.java:876) at org.eclipse.ui.internal.Workbench.updateActiveWorkbenchWindowMenuManager(Workbench.java:3278) at org.eclipse.ui.internal.Workbench.access$0(Workbench.java:3238) at org.eclipse.ui.internal.Workbench$2.bindingManagerChanged(Workbench.java:3224) at org.eclipse.jface.bindings.BindingManager.fireBindingManagerChanged(BindingManager.java:900) at org.eclipse.jface.bindings.BindingManager.setActiveBindings(BindingManager.java:2176) at org.eclipse.jface.bindings.BindingManager.clearSolution(BindingManager.java:442) at org.eclipse.jface.bindings.BindingManager.schemeChanged(BindingManager.java:2132) at org.eclipse.jface.bindings.Scheme.fireSchemeChanged(Scheme.java:186) at org.eclipse.jface.bindings.Scheme.undefine(Scheme.java:287) at org.eclipse.ui.internal.keys.BindingPersistence.readSchemesFromRegistry(BindingPersistence.java:1046) at org.eclipse.ui.internal.keys.BindingPersistence.reRead(BindingPersistence.java:1405) at org.eclipse.ui.internal.menus.WorkbenchMenuService.handleRegistryChanges(WorkbenchMenuService.java:1106) at org.eclipse.ui.internal.menus.WorkbenchMenuService$2.run(WorkbenchMenuService.java:274) at org.eclipse.ui.internal.UILockListener.doPendingWork(UILockListener.java:164) at org.eclipse.ui.internal.UISynchronizer$3.run(UISynchronizer.java:158) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4041) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3660) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:369) 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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) Reproducible: Always Steps to Reproduce: click on "Run Configuration..."
Apart from standard SDK, have you installed any other plugins?
Subclipse, GWT,
I also see the following in the error log: java.lang.NullPointerException at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationsDialog.updateButtons(LaunchConfigurationsDialog.java:1518) at org.eclipse.debug.ui.AbstractLaunchConfigurationTab.updateLaunchConfigurationDialog(AbstractLaunchConfigurationTab.java:100) at org.eclipse.debug.ui.AbstractLaunchConfigurationTab$1.runInUIThread(AbstractLaunchConfigurationTab.java:423) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:95) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4041) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3660) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
I suspect GWT plugin. Can you try Eclipse without it and let us know whether its reproducible?
It happens also without GWT
Assigning to Debug for investigation.
(In reply to comment #3) > I also see the following in the error log: Please attach the error log, preferable when the one that includes the first Undefined Context warning. Did you install the software (GWT, etc) and then hit "Apply Now"? But you mentioned you installed without GWT and had the same problem, and it's not the kind of thing that should survive restarts. Your install without GWT, is it an OS package (like on linux) or did you unzip/untar something from download.eclipse.org? In this case "org.eclipse.ui.externaltools.ExternalToolsSet" is a context defined for an actionSet, and its parent context is "org.eclipse.ui.contexts.actionSet" PW
Please provide full log and reopen. One oddity here is that the given trace in comment #3 points to line (1518) in LaunchConfigurationsDialog, which doesn't exist.
