Fixed > 20051003. Released in HEAD for 3.2 stream. For eclipse 3.1, the work-around is simply to use the +/- to expand/collapse the tree, instead of double-clicking on a category. Steve to decide whether or not this (simple) fix should be back-ported to eclipse 3.1, seeing as how the examples are fairly visible.
Marking for 3.2 M3 for now, anyway.
To be clear, it's a bug in the example, right?
Yes.
Ok, put it in the 3.1.x stream.
Done (there's no 3.1.2 target milestone yet in bugzilla, hope I remember to mark this as such when there is).
Marking 3.1.2.
