Tree problem...

[Filip Balas <fb...@IMVProjects.com>]

I'm trying to change the model for
a tree in response to a user selecting
something from a combo box.

Every time I regenerate the model
(and I have verified that the model
is created properly and that it is not
null) and attempt to click on the root
node to expand the tree I recieve a 
null pointer exception.

Can you do this? or is there some other
snazzy way of re-initializing a tree component?
