Build Identifier: 20110615-0604 after beeing hit by a NullPointerException i checked the code of FilteredPreferenceDialog and found following problem: the class variable "filteredTree" is only initialized in one point, within an if-clause (line 233), but is used in showOnly(...) without checking if it is actually initialized, what caused the NullPointerException in my situation. public void showOnly(String[] filteredIds) { filteredTree.addFilter(new PreferenceNodeFilter(filteredIds)); } cheers marco Reproducible: Always

background info: I'm currently working on a plugin that provides extensions to emf model validation (org.eclipse.emf.validation) These show up on the preferences page under "model validation / constraints". The preferences page is displayed correctly when I open it using the menu (window/preferences). The problem shows up when using certain papyrus (org.eclipse.papyrus) model validation options. Right-clicking on an opened model in the model explorer and then choosing "validation -> select constraints and validate model" is supposed to bring up a filtered preferences page only showing the model validation constraints. this is when the exception occurs. java.lang.NullPointerException at org.eclipse.ui.internal.dialogs.FilteredPreferenceDialog.showOnly(FilteredPreferenceDialog.java:356) at org.eclipse.ui.dialogs.PreferencesUtil.applyOptions(PreferencesUtil.java:75) at org.eclipse.ui.dialogs.PreferencesUtil.createPreferenceDialogOn(PreferencesUtil.java:194) at org.eclipse.ui.dialogs.PreferencesUtil.createPreferenceDialogOn(PreferencesUtil.java:116) at org.eclipse.papyrus.modelexplorer.commands.SelectAndValidateModelCommand.doExecuteWithResult(SelectAndValidateModelCommand.java:47) at org.eclipse.gmf.runtime.emf.commands.core.command.AbstractTransactionalCommand.doExecute(AbstractTransactionalCommand.java:247) at org.eclipse.emf.workspace.AbstractEMFOperation.execute(AbstractEMFOperation.java:150) at org.eclipse.papyrus.modelexplorer.handler.GMFtoEMFCommandWrapper.execute(GMFtoEMFCommandWrapper.java:96) at org.eclipse.emf.workspace.EMFCommandOperation.doExecute(EMFCommandOperation.java:119) at org.eclipse.emf.workspace.AbstractEMFOperation.execute(AbstractEMFOperation.java:150) at org.eclipse.core.commands.operations.DefaultOperationHistory.execute(DefaultOperationHistory.java:513) at org.eclipse.emf.workspace.impl.WorkspaceCommandStackImpl.doExecute(WorkspaceCommandStackImpl.java:208) at org.eclipse.emf.transaction.impl.AbstractTransactionalCommandStack.execute(AbstractTransactionalCommandStack.java:165) at org.eclipse.emf.transaction.impl.AbstractTransactionalCommandStack.execute(AbstractTransactionalCommandStack.java:219) at org.eclipse.papyrus.modelexplorer.handler.AbstractCommandHandler.execute(AbstractCommandHandler.java:150) at org.eclipse.ui.internal.handlers.HandlerProxy.execute(HandlerProxy.java:293) at org.eclipse.core.commands.Command.executeWithChecks(Command.java:476) at org.eclipse.core.commands.ParameterizedCommand.executeWithChecks(ParameterizedCommand.java:508) at org.eclipse.ui.internal.handlers.HandlerService.executeCommand(HandlerService.java:169) at org.eclipse.ui.internal.handlers.SlaveHandlerService.executeCommand(SlaveHandlerService.java:241) at org.eclipse.ui.internal.handlers.SlaveHandlerService.executeCommand(SlaveHandlerService.java:241) at org.eclipse.ui.menus.CommandContributionItem.handleWidgetSelection(CommandContributionItem.java:829) at org.eclipse.ui.menus.CommandContributionItem.access$19(CommandContributionItem.java:815) at org.eclipse.ui.menus.CommandContributionItem$5.handleEvent(CommandContributionItem.java:805) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4165) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3754) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2696) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2660) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) 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:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386)
