Hi,
I have a RCP which loads the graphiti Editor post startup and initializes it with a default diagram. The resources of the diagram are also saved to disk. Everything works fine, except the editor is marked dirty
(and probably due to this a emf exception after creating a new model object and saving afterwards -> java.lang.IllegalStateException: Cannot modify resource set without a write transaction).
here are some code snippets for better understanding.
within the postStartup method in my ApplicationWorkbenchAdvisor:
URI uri = URI.createPlatformResourceURI(diagramFile.getFullPath().toString(), true);
TransactionalEditingDomain domain = FileService.createEmfFileForDiagram(uri, diagram);
String providerId = GraphitiUi.getExtensionManager().getDiagramTypeProviderId(diagram.getDiagramTypeId());
editorInput = new DiagramEditorInput(EcoreUtil.getURI(diagram), domain, providerId, true);
try {
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().openEditor(editorInput, editorID);
} catch (PartInitException e) {
LOG.error("Error while opening diagram editor", e);
}
The method createEmfFileForDiagrampublic static TransactionalEditingDomain createEmfFileForDiagram(URI diagramResourceUri, final Diagram diagram) {
final TransactionalEditingDomain editingDomain = DiagramEditorFactory.createResourceSetAndEditingDomain();
final ResourceSet resourceSet = editingDomain.getResourceSet();
URI modelResourceUri = diagramResourceUri.trimFragment().
trimFileExtension().appendFileExtension(OtxPackage.eNS_PREFIX);
final Resource modelResource = resourceSet.createResource(modelResourceUri);
final Resource diagramResource = resourceSet.createResource(diagramResourceUri);
final CommandStack commandStack = editingDomain.getCommandStack();
commandStack.execute(new RecordingCommand(editingDomain) {
@Override
protected void doExecute() {
modelResource.setTrackingModification(true);
diagramResource.setTrackingModification(true);
diagramResource.getContents().add(diagram);
try {
EObject rootObject = OtxUtil.createDefaultOtxSkeleton();
modelResource.getContents().add(rootObject);
Map<Object, Object> options = new HashMap<Object, Object>();
options.put(XMLResource.OPTION_ENCODING, "UTF-8");
modelResource.save(options);
diagramResource.save(Collections.EMPTY_MAP);
} catch(IOException ioe) {
ioe.printStackTrace();
} catch (DatatypeConfigurationException e) {
e.printStackTrace();
}
}
});
return editingDomain;
}
So what do i have to do for not marking the editor dirty)?
thx!

thanks, that resolved the "marked dirty" issue! (see new createEmfFileForDiagram () method below)
But the other problem was not solved.
After creating a new model object and saving afterwards, i get:java.lang.IllegalStateException: Cannot modify resource set without a write transaction
public static TransactionalEditingDomain createEmfFileForDiagram(
URI diagramResourceUri, final Diagram diagram) {
final TransactionalEditingDomain editingDomain = DiagramEditorFactory
.createResourceSetAndEditingDomain();
final ResourceSet resourceSet = editingDomain.getResourceSet();
URI modelResourceUri = diagramResourceUri.trimFragment()
.trimFileExtension().appendFileExtension(OtxPackage.eNS_PREFIX);
final Resource modelResource = resourceSet
.createResource(modelResourceUri);
final Resource diagramResource = resourceSet
.createResource(diagramResourceUri);
final CommandStack commandStack = editingDomain.getCommandStack();
final Map<Resource, Map<?, ?>> resourceOptionsMap = new HashMap<Resource, Map<?, ?>>();
commandStack.execute(new RecordingCommand(editingDomain) {
@Override
protected void doExecute() {
modelResource.setTrackingModification(true);
diagramResource.setTrackingModification(true);
diagramResource.getContents().add(diagram);
try {
EObject rootObject = OtxUtil.createDefaultOtxSkeleton();
modelResource.getContents().add(rootObject);
Map<Object, Object> options = new HashMap<Object, Object>();
options.put(XMLResource.OPTION_ENCODING, "UTF-8");
resourceOptionsMap.put(modelResource, options);
resourceOptionsMap.put(diagramResource, Collections.EMPTY_MAP);
} catch (DatatypeConfigurationException e) {
e.printStackTrace();
}
}
});
save(editingDomain, resourceOptionsMap);
return editingDomain;
}

You need to do perform every change operation to your model inside an EMF
transaction, that will solve this issue.
HTH,

get:java.lang.IllegalStateException: Cannot modify resource set without a

thread, if i cannot figure it out myself.
