I'm getting the same behavior as both of you. I get it with
@action and @actionListener . I get it with the HEAD branch
and 1.0.9 . I get it when I add nodes and remove nodes.
I'll take a look this weekend. If there aren't any bright
ideas between now and next week, I'll open a bug so that we
can discuss this at the "tree2 summit" .

Maybe "<x:tree2

correctly on the
