If a user uninstalls some plugins or maybe migrates to a new version and then opens a workspace which have some editors open, they can hit an exception like the following. While this exception is perhaps useful for those developing eclipse products, I would argue that it is unnecessary alarmist and confusing from user's perspective. A much better end-user behavior would be to not treat this as a failure and just skip restoring that editor. org.eclipse.ui.PartInitException: No editor descriptor for id oracle.eclipse.tools.weblogic.ui.ddeditor.internal.WebLogicDescriptorEditor at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java: 598) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:462) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference. java:595) at org.eclipse.ui.internal.PartPane.setVisible(PartPane.java:313) at org.eclipse.ui.internal.presentations.PresentablePart.setVisible(PresentablePa rt.java:180) at org.eclipse.ui.internal.presentations.util.PresentablePartFolder.select(Presen tablePartFolder.java:270) at org.eclipse.ui.internal.presentations.util.LeftToRightTabOrder.select(LeftToRi ghtTabOrder.java:65) at org.eclipse.ui.internal.presentations.util.TabbedStackPresentation.selectPart( TabbedStackPresentation.java:473) at org.eclipse.ui.internal.PartStack.refreshPresentationSelection(PartStack.java: 1256) at org.eclipse.ui.internal.PartStack.setSelection(PartStack.java:1209) at org.eclipse.ui.internal.PartStack.presentationSelectionChanged(PartStack.java: 843) at org.eclipse.ui.internal.PartStack.access$1(PartStack.java:829) at org.eclipse.ui.internal.PartStack$1.selectPart(PartStack.java:139) at org.eclipse.ui.internal.presentations.util.TabbedStackPresentation$1.handleEve nt(TabbedStackPresentation.java:133) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder.fireEvent(Abstrac tTabFolder.java:270) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder.fireEvent(Abstrac tTabFolder.java:279) at org.eclipse.ui.internal.presentations.defaultpresentation.DefaultTabFolder.acc ess$1(DefaultTabFolder.java:1) at org.eclipse.ui.internal.presentations.defaultpresentation.DefaultTabFolder$2.h andleEvent(DefaultTabFolder.java:87) 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.Widget.sendEvent(Widget.java:1027) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1012) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:770) at org.eclipse.swt.custom.CTabFolder.setSelection(CTabFolder.java:3256) at org.eclipse.swt.custom.CTabFolder.onMouse(CTabFolder.java:2045) at org.eclipse.swt.custom.CTabFolder$1.handleEvent(CTabFolder.java:323) 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:3880) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3473) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2405) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2369) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.ja va:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:19 4) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(Ec lipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppL auncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:368) 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.j ava:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:559) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:514) at org.eclipse.equinox.launcher.Main.run(Main.java:1311) at org.eclipse.equinox.launcher.Main.main(Main.java:1287)
Eric was looking at dealing with missing views,editors,perspectives on restart in some "graceful" manner, IIRC. PW
Remy is now responsible for watching the [EditorMgmt] component area.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
