[flexcoders] Tree ItemClose

[vitorinomarlene]

Hello,
I'm trying to acomplish the following tree behavior:
A tree node can only be closed if their children are leafs or if their
children are closed. I've added handlers for itemClose, and through
the event.item i can acces the node data (the xml data of the closed
item), but i don't know how to check wether the corresponding tree
node has children and if these children are open or closed. Thank you
very much
