I was trying to create an AWT Dialog. This doesnt work, I assume this is the problem: java.lang.NullPointerException at org.eclipse.emf.ecore.impl.EStructuralFeatureImpl.getSettingDelegate(EStructuralFeatureImpl.java:790) at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eSettingDelegate(BasicEObjectImpl.java:822) at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eDynamicIsSet(BasicEObjectImpl.java:609) at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eIsSet(BasicEObjectImpl.java:600) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveFeatures(XMLSaveImpl.java:951) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveElementID(XMLSaveImpl.java:2272) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveElement(XMLSaveImpl.java:889) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveContainedMany(XMLSaveImpl.java:2001) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveFeatures(XMLSaveImpl.java:1221) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.saveElementID(XMLSaveImpl.java:2272) at org.eclipse.emf.ecore.xmi.impl.XMISaveImpl.writeTopObjects(XMISaveImpl.java:78) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.traverse(XMLSaveImpl.java:478) at org.eclipse.emf.ecore.xmi.impl.XMLSaveImpl.save(XMLSaveImpl.java:206) at org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.doSave(XMLResourceImpl.java:193) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:893) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:813) at org.eclipse.ve.internal.java.codegen.util.VEModelCacheUtility.doSaveCache(VEModelCacheUtility.java:158) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.doSave(JavaSourceTranslator.java:1358) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator$2.doRun(JavaSourceTranslator.java:923) at org.eclipse.ve.internal.java.codegen.util.ReverseParserJob.run(ReverseParserJob.java:56) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:76) eclipse.buildId=M20050929-0840 java.version=1.5.0_06 java.vendor=Sun Microsystems Inc.

I'll transfer this to VE. I'll need a self contained reproducible test case to address this as an EMF problem.
We've had some cache problems in VE. Please do the following: Step up to Eclipse 3.2M4, EMF 2.2M4, GEF 3.2M4 and VE 1.2 I20060203. Then do the following to clear the cache. 1) Open a VE but then close it and all other VE's. 2) Do Project->Clean...->Clean All... and wait for the build to complete 3) Open the VE again and see if it now works. Thanks.
I followed your instructions. Finally, when opening the VE for my class nothing appears in the VE Pane, but I got exceptions in the error log: org.eclipse.emf.common.util.WrappedException: org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'size' not found.

I made a mistake. It should of been VE I20060202. The one I gave you is for working against Eclipse I20060131, not 3.2M4. But I don't think that is the problem. This still indicates a cache problem. Clean the cache one more time, please. But before you open the VE after cleaning the cache, erase the .log file. That way there won't be any stuff hanging around. This error shows it had written the cache at least once. That should not of occured on the first opening after a cache clear. Are you sure you opened a VE, closed ALL VE's, did a Project->Clean...->Clean ALL projects, waited for build to complete? This must be done in one Eclipse session, you mustn't close Eclipse down in between.
I replaced the VE Build as you told. I interpret "open a VE" as "open a java file in VE Editor". I opened a VE, closed all editor panes, made a "clean all projects", opened the java file again in VE editor and got this result: !ENTRY org.eclipse.ve.java.core 2 0 2006-02-14 20:00:40.362 !MESSAGE Exception thrown. !STACK 0 java.lang.NullPointerException at org.eclipse.ve.internal.java.codegen.util.WorkingCopyProvider.getEditor(WorkingCopyProvider.java:96) at org.eclipse.ve.internal.java.codegen.util.WorkingCopyProvider.getDocument(WorkingCopyProvider.java:140) at org.eclipse.ve.internal.java.codegen.java.JavaSourceSynchronizer.connect(JavaSourceSynchronizer.java:226) at org.eclipse.ve.internal.java.codegen.java.JavaSourceSynchronizer.<init>(JavaSourceSynchronizer.java:99) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.reConnect(JavaSourceTranslator.java:1109) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.decodeDocument(JavaSourceTranslator.java:895) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.loadModel(JavaSourceTranslator.java:590) at org.eclipse.ve.internal.java.codegen.editorpart.JavaVisualEditorPart$Setup.run(JavaVisualEditorPart.java:1971) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) !ENTRY org.eclipse.jdt.core 4 969 2006-02-14 20:00:40.402 !MESSAGE __projectWorkingcopy__ does not exist Just another point: The default java editor pane looks strange in the 3.2M4 eclipse - I dont have line numbers, error marks, breakpoints in it anymore. 'F3' for Open declaration leads to Info-Message "The resource is not on the build path of a java project" (of course it is, it was all the time)
This means your class is not within the source folder of the java project. Either your project is not a java project or your file is not within a source folder in the project. That would cause the NPE you are getting.
The projects I have are all Java projects (I have the small 'J' over their icons, and in the project properties have Java Build path etc.) I have a source folder in it and the packages are listed correctly. So If there is something wrong I can't see it actually. there are no compile errors in the projects (at least not in the compile-ready ones)
