No visual window is shown (for any of the visual classes). The only things that appear in the visual part are icons of "this" and "sShell" (without "X"s on them), and not error is shown in the status bar. Looking at the log file, there a lot of exceptions, but they don't re-occur. They are just written the first time after an eclipse restart, but not afterwards. The problem started happening after an eclipse crash. Cleaning the cache did not work. The problem remains. !ENTRY org.eclipse.ve.java.core 4 0 2006-10-29 02:30:02.062 !MESSAGE Exception thrown. !STACK 0 java.lang.ArrayIndexOutOfBoundsException: -1 at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:514) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObjectForURIFragmentRootSegment(ResourceImpl.java:642) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObject(ResourceImpl.java:692) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.getEObject(ResourceImpl.java:671) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.setValueFromId(XMLHandler.java:2511) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.setAttribValue(XMLHandler.java:2439) at org.eclipse.emf.ecore.xmi.impl.SAXXMIHandler.handleObjectAttribs(SAXXMIHandler.java:74) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.createObjectFromFactory(XMLHandler.java:1929) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.createObjectFromTypeName(XMLHandler.java:1833) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.createObject(XMLHandler.java:1768) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.handleFeature(XMLHandler.java:1576) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.processElement(XMLHandler.java:876) at org.eclipse.emf.ecore.xmi.impl.XMIHandler.processElement(XMIHandler.java:82) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.startElement(XMLHandler.java:854) at org.eclipse.emf.ecore.xmi.impl.XMLHandler.startElement(XMLHandler.java:626) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:533) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:330) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1693) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:764) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:148) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1242) at javax.xml.parsers.SAXParser.parse(SAXParser.java:375) at org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.load(XMLLoadImpl.java:179) at org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.doLoad(XMLResourceImpl.java:179) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.load(ResourceImpl.java:1089) at org.eclipse.emf.ecore.resource.impl.ResourceImpl.load(ResourceImpl.java:895) at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoad(ResourceSetImpl.java:249) at org.eclipse.jem.internal.util.emf.workbench.ProjectResourceSetImpl.demandLoad(ProjectResourceSetImpl.java:83) at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:264) at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:390) at org.eclipse.jem.internal.util.emf.workbench.ProjectResourceSetImpl.getResource(ProjectResourceSetImpl.java:262) at org.eclipse.ve.internal.java.codegen.util.VEModelCacheUtility.doLoadFromCache(VEModelCacheUtility.java:103) at org.eclipse.ve.internal.java.codegen.core.VEModelInstance.createComposition(VEModelInstance.java:100) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.reConnect(JavaSourceTranslator.java:1134) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.decodeDocument(JavaSourceTranslator.java:910) at org.eclipse.ve.internal.java.codegen.core.JavaSourceTranslator.loadModel(JavaSourceTranslator.java:597) at org.eclipse.ve.internal.java.codegen.editorpart.JavaVisualEditorPart$Setup.run(JavaVisualEditorPart.java:1978) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) !ENTRY org.eclipse.ve.java.core 2 0 2006-10-28 04:26:22.140 !MESSAGE Exception thrown. !STACK 0 org.eclipse.ve.internal.java.core.IAllocationProcesser$AllocationException: java.lang.IllegalArgumentException: IWAV0177E Expression "ti" is too complicated. -

As part of some general bugzilla cleanup, I am marking all old JEM bugs as "won't fix" simply because JEM is in maintenance mode, and there are no plans to fix these old bugs. If I have mistaken marked something that is still a current problem in the latests releases from WTP, please re-open.
Moving that bug to VE.
