Hello,
I am getting the following exception running the line below in a Java standalone project while I have imported gmf dependencies as source codes of the installed gmf plugin. I am using the latest Eclipse.
Could you please guide me how to fix this?
Thanks,

Diagram diagram = ViewService.createDiagram(1,
new PreferencesHint(""));
