Hi. Do you guys know how can I get the EditPart from its correspondent Impl model? Actually, I should change some attributes in run time, so I create a request. But in the code below, I should at first create "selection" which is a EditPart element.

        IGraphicalEditPart editpart = (IGraphicalEditPart) selection;
        SetRequest requestTirerTransition = new SetRequest(
                editpart.getEditingDomain(),
                ViewUtil.resolveSemanticElement((View) editpart.getModel()),//The semantic model 
                RdpPackage.Literals.TRANSITION__TIRER,//Name feature of activity      
                1);//New name value

        SetValueCommand command = new SetValueCommand(requestTirerTransition);
        editpart.getDiagramEditDomain().getDiagramCommandStack().execute(new ICommandProxy(command));

Do you have any ideas?
Thanks

Vincent

Hi,

do I understand right that selection is null and this is your problem? If yes where do you want to execute the code from? What do you mean by Impl model?

Hi, Ralph.

Thank you for you answers. I have resolved it. Because I want to change the color of a node in run time, so that I create a request. But it need a EditPart class rather than a Impl class. Using the code below, I can get all the EditParts in my model.

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
        if (page != null) {
            IEditorPart editor = page.getActiveEditor();
            if (editor instanceof GraphicalEditor) {
                GraphicalEditor graphicalEditor = (GraphicalEditor) editor;
                rootEditPart[0] = (RootEditPart) graphicalEditor.getAdapter(EditPart.class);
            }
        }
