[news.eclipse.modeling.gmf] [Solved] Layout information persistence

[bolah@xxxxxxxxxxxxxxxxxxx (Bence Oláh)]

I have overriden the 
XXXMetamodelDiagramEditor.initializeGraphicalViewerContents() method to 
execute an auto-layout command and then the diagram file is saved:

Sample: 
@Override
protected void initializeGraphicalViewerContents() {
 super.initializeGraphicalViewerContents();

 ArrangeRequest arrangeRequest = new 
ArrangeRequest(ActionIds.ACTION_ARRANGE_ALL);
 IGraphicalEditPart rootEP = (IGraphicalEditPart) 
getDiagramGraphicalViewer().getRootEditPart().getContents();
 List l = new ArrayList();
 l.add(rootEP);
 arrangeRequest.setPartsToArrange(l);
 Command cmd = rootEP.getCommand(arrangeRequest);
 // execute command
 getCommandStack().execute(cmd);

 // save the file
 performSave(true, new NullProgressMonitor());
}

After the auto-layout I can get all the tranformation relevant infromation!
