> I couldn't find a bug for this and I am having the same problem.  I've done a little
resarch and I think I understand the problem.  
> The tree2 js stores the tree state in a cookie named with the component id.  I have a
page where the tree changes between requests.  Because the rest of the page is the same, the
component id does not change.  The js tries to open up the same nodes as was open in the old
tree.  The problem occurs when the new tree has a leaf node that was not a leaf in the old
tree and was open in the old tree.  I get this error "java.lang.IllegalStateException: Encountered
a node [0:0:0] + with an illogical state.  Node is expanded but it is also considered a leaf".
> For me, I could get around this problem if I could name the component (or the cookie)
dynamically using a managed bean value.  Since I cannot name the id in this manner, I have
a problem.
> Maybe a solution would be a new paramerter to specify the cookie name.
> Thanks!  Here is the full stack trace....

 Node is expanded but it is also considered a leaf (a leaf cannot be considered expanded.
