Description Cedric Brun CLA 2014-06-12 05:00:15 EDT 
When a user try to create a Diagram from an .ecore file from the Java perspective (or any other perspective which will not trigger the instanciation of the Sirius content providers) the wizard fails with a NPE.

are introducing a workaround to this : explicitely "preparing the work" for Sirius with calls to 
		IEditingSession uiSession = SessionUIManager.INSTANCE
				.getOrCreateUISession(existingSession);
		uiSession.open();

It is built in http://download.eclipse.org/ecoretools/updates/nightly/2.0.0-N20140612-043843 and has been tested successfully on windows.
Comment 2 Cedric Brun CLA 2014-06-26 08:49:50 EDT 
The workaround is shipped through http://download.eclipse.org/ecoretools/updates/nightly/2.0.x/luna and through the discovery view in the modeling package.
