Opening instance of .ecore in GMF diagram [message #668429]

Hey everyone,

I got into a little trouble trying to programmatically open an instance of my ecore model in a gmf-diagram. The instance I would like to display is in a Resource and I try to open it in a rcp application.

I have already tried this:

MyDiagramEditorUtil.openDiagram(myResource);

but this causes this error:

	java.lang.NullPointerException
	at org.eclipse.core.runtime.Path.<init>(Path.java:153)
	at my.diagram.part.MyDiagramEditorUtil.openDiagram(MyDiagramEditorUtil.java:82)

DiagramEditorUtil seems like a good starting point for my approach, e.g. using the runWizard() method worked fine, but I do not want to use this wizard. Or am I totally wrong at this point?

Hope someone could help. Thanks upfront

Best regards,
David

URI newURI = URI.createURI("file:/C:/xyz");
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
try {
   page.openEditor(new URIEditorInput(newURI), XYZ.diagram.part.XYZDiagramEditor.ID);
} catch (PartInitException e) {
   e.printStackTrace();
}

Or get the URI from the resource that you have. Not sure if this is the correct way to do it, but you could give it a try...
