I get NPEs while trying to type and search for the contribution class from the model editor.

Remy: I'm unable to reproduce this myself, but looking at the code, it seems to assume that the active project will have a java nature.  Is it possible you were using a non-Java project?

I don't think I had a single project around because I was in a new workspace.

Remy said this arises from using the *live* editor.  I've been able to reproduce this.

Comment 4 Nobody - feel free to take it

There's a null check now.
