Its been a while since I worked on tree2 but I'm planning to get back
to it soon now that the maven stuff is mostly finished.
You said all of the nodes unselected but only one node can be selected
at a time. Did you mean collapsed instead? If you really did mean
unselected, unfortunately the selected status is only easily
accessible through the action event (which knows to apply itself to
the correct node.)
A while back we introduced TreeState and TreeModel interfaces.
Unfortunately that only helps you with expand/collapse. I need to get
back to MYFACES-911 which will add a lot of new flexability to tree2.
Unfortunately the patch is now broken because of the maven reorg so I
need to rework it.
