Build Identifier: 20100917-0705 As soon as I reference the OCL metamodel by adding usedGenPackages="platform:/plugin/org.eclipse.emf.ecore/model/Ecore.genmodel#//ecore platform:/plugin/org.eclipse.ocl/model/OCL.genmodel#//ocl platform:/plugin/org.eclipse.ocl.ecore/model/OCLEcore.genmodel#//ocl" to my genmodel file, the editor crashes with the following stack trace: java.lang.NullPointerException at org.eclipse.emf.codegen.ecore.genmodel.impl.GenBaseImpl.findGenPackageHelper(GenBaseImpl.java:870) at org.eclipse.emf.codegen.ecore.genmodel.impl.GenModelImpl.findGenPackage(GenModelImpl.java:1839) at org.eclipse.emf.codegen.ecore.genmodel.impl.GenModelImpl.computeMissingUsedGenPackages(GenModelImpl.java:8651) at org.eclipse.emf.codegen.ecore.genmodel.impl.GenModelImpl.reconcile(GenModelImpl.java:8591) at org.eclipse.emf.codegen.ecore.genmodel.presentation.GenModelEditor.initialize(GenModelEditor.java:594) at org.eclipse.emf.codegen.ecore.genmodel.presentation.GenModelEditor.createPages(GenModelEditor.java:1080) at org.eclipse.ui.part.MultiPageEditorPart.createPartControl(MultiPageEditorPart.java:348) at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:670) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:465) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.EditorReference.getEditor(EditorReference.java:289) at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditorBatched(WorkbenchPage.java:2863) at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditor(WorkbenchPage.java:2768) at org.eclipse.ui.internal.WorkbenchPage.access$11(WorkbenchPage.java:2760) at org.eclipse.ui.internal.WorkbenchPage$10.run(WorkbenchPage.java:2711) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:70) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2707) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2691) at org.eclipse.ui.actions.OpenWithMenu.openEditor(OpenWithMenu.java:331) at org.eclipse.ui.actions.OpenWithMenu$2.handleEvent(OpenWithMenu.java:179) 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:4066) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3657) 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(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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) My plugin correctly depends on the respective OCL plugins. Reproducible: Always Steps to Reproduce: 1. Reference the OCL and OCLEcore metamodels with usedGenPackages 2. Open the genmodel file in the "EMF Generator" 3. The editor crashes
I can't reproduce a problem with these usedGenPackage references. I can't even reproduce a problem when I add references to packages that I know don't resolve. The only way this could happen, apparently, is if you have GenPackages with null .getEcorePackage() so I added a guard for that. Even with the guard, you'll be needing to fix whatever is bogus in your file, so don't expect fixes in a maintenance stream.
The fix is available in the latest build for the stream.
