Please install the Ecore tools in e4 as described here: http://www.vogella.de/articles/EclipseEMF/article.html#emfinstallation Follow then the creation of an EMF model via the Ecore tools (should only take 5 minutes): http://www.vogella.de/articles/EclipseEMF/article.html#createmodel Delete on part from the diagram, via right mouse menu-> remove from model -> you receive a SWTException. org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:4091) at org.eclipse.swt.SWT.error(SWT.java:4006) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:137) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4059) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3678) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$6.run(PartRenderingEngine.java:783) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:692) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:104) at org.eclipse.ui.internal.Workbench$3.run(Workbench.java:542) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:524) 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:621) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:576) at org.eclipse.equinox.launcher.Main.run(Main.java:1409) at org.eclipse.equinox.launcher.Main.main(Main.java:1385) Caused by: java.lang.NullPointerException at org.eclipse.emf.ecoretools.diagram.edit.policies.EcoreBaseItemSemanticEditPolicy.addDestroyShortcutsCommand(EcoreBaseItemSemanticEditPolicy.java:351) at org.eclipse.emf.ecoretools.diagram.edit.policies.EClassItemSemanticEditPolicy.getDestroyElementCommand(EClassItemSemanticEditPolicy.java:64) at org.eclipse.emf.ecoretools.diagram.edit.policies.EcoreBaseItemSemanticEditPolicy.getSemanticCommandSwitch(EcoreBaseItemSemanticEditPolicy.java:184) at org.eclipse.emf.ecoretools.diagram.edit.policies.EcoreBaseItemSemanticEditPolicy.getSemanticCommand(EcoreBaseItemSemanticEditPolicy.java:124) at org.eclipse.gmf.runtime.diagram.ui.editpolicies.SemanticEditPolicy.getCommand(SemanticEditPolicy.java:69) at org.eclipse.emf.ecoretools.diagram.edit.policies.EcoreBaseItemSemanticEditPolicy.getCommand(EcoreBaseItemSemanticEditPolicy.java:106) at org.eclipse.gef.editparts.AbstractEditPart.getCommand(AbstractEditPart.java:501) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart.access$1(GraphicalEditPart.java:1) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart$1.run(GraphicalEditPart.java:482) at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.runExclusive(TransactionalEditingDomainImpl.java:328) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart.getCommand(GraphicalEditPart.java:477) at org.eclipse.emf.ecoretools.diagram.part.DeleteElementAction.getCommand(DeleteElementAction.java:84) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.getCommand(DiagramAction.java:161) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.calculateEnabled(DiagramAction.java:124) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.refresh(DiagramAction.java:114) at org.eclipse.gmf.runtime.common.ui.action.AbstractActionHandler.selectionChanged(AbstractActionHandler.java:387) at org.eclipse.gmf.runtime.diagram.ui.parts.DiagramGraphicalViewer.flushSelectionEvents(DiagramGraphicalViewer.java:269) at org.eclipse.gmf.runtime.diagram.ui.parts.DiagramGraphicalViewer$1.run(DiagramGraphicalViewer.java:247) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) ... 24 more
Lars, are you testing org.eclipse.emf.ecoretools_0.10.0.v20100615-1639 with 4.1 M3? PW
I used the Indigo site but was unable to complete step 3.2 because the 'Ecore Diagram' wizard is not in my list.
I'd get the code myself but can't seem to find the GMF code. The (now defunct?) sources seems to indicate it's in /cvsroot/modeling but I don't see any org.eclipse.gmf/ modules there.
(In reply to comment #3) > The (now defunct?) > sources seems to indicate it's in /cvsroot/modeling but I don't see any > org.eclipse.gmf/ modules there. Looks like they're in org.eclipse.gmp/ now. Will poke in there...
Paul, I'm using Eclipse 4.1 M3 with Ecore Tools Utilities (Incubation) 0.10.0.v20100601-1628. Hope this helps, Lars
(In reply to comment #5) > I'm using Eclipse 4.1 M3 with Ecore Tools Utilities (Incubation) > 0.10.0.v20100601-1628. I don't see this on the Galileo, Helios, or Indigo sites. Which update site should I use? ._.

The Ecore Diagram wizard doesn't show up in the current I builds because of 1) the OSGi changes + 2) the fixing of batik. org.apache.batik.util=1.6.0.v200805290154 org.apache.batik.util=1.6.0.v201011041432 org.apache.batik.util.gui=1.6.0.v200805290154 org.apache.batik.util.gui=1.6.0.v201011041432 org.apache.batik.util.gui.source=1.6.0.v200805290154 org.apache.batik.util.source=1.6.0.v200805290154 The v201011041432 version is incompatible with v200805290154, and ecoretools/gmf depend on a lot of batik plugins that need the v200805290154 version. PW
(In reply to comment #8) > The Ecore Diagram wizard doesn't show up in the current I builds because of 1) > the OSGi changes + 2) the fixing of batik. I have opened bug 331471 against Ecore Tools for this.
The EditPart that the DeleteElementAction gets is an EClassEditPart on 4.x but is an EPackageEditPart in the 3.x case.
Thanks for the report, Lars, I have corrected bug 333589.
I think this one is closed in Eclipse 4.2
