I am looking for a way to open a Custom Graphiti Editor (e3.x) in my e4 application.

Dirk Fahland recommends in his tutorial to use an e3.x application and add an e4-product on top of it for this purpose, see
I tried this and it turned out that many of the nice e4 features did not work anymore (for example defining the main menu or handlers in the Application.e4xmi).

Basically I am looking for an e4 equivalent for the following openFile-Handler:

	public Object execute(ExecutionEvent event) throws ExecutionException {
		URI uri = URI.createFileURI("N:/testdiagrams/test.filedi");
		URIEditorInput editorInput = new URIEditorInput(uri);
		IWorkbenchPage page = HandlerUtil.getActiveWorkbenchWindow(event).getActivePage();
		page.openEditor(editorInput, "MyProject.graphitieditor");
		return null;

What is the best way to achieve opening a file with my editor without giving up so much of the concept of defining the components in Application.e4xmi?

Maybe our migration tutorial helps. Unfortunately it is currently only available in German but we think about translating it soon.

But maybe the examples or the related GitHub project gives some ideas
