Hi Volker:
It does not matter you have checked the box or not, it still
picked up the entire leafs that was being save from the database. My
purpose is able to unchecked the one that I would like to remove it from
the existing leafs? Is there a way to do this? Thanks again.

Hi Volker:
I put it in action command or action method and it did pick up
the unchecked leafs. Thank you very much.

the getter of the TreeState is imho the wrong place to capture the
selection.
this should be done in the action method werd the result is stored.
the way you do this is ok, but you will get the selection before
rendering, not the one after submitting the page.
