Hi,

I have a TreePanel in my Application. The root of the tree is an AsyncTreeNode. Expanding this node takes a lot of time, because there are many nodes at the next level and the PHP-Script providing this nodes takes a lot of time to put them together (2-3 sec).
In the tree configuration I set 'rootVisible' to false. So while the tree is loading, the user can see only a white panel.
How can I show an alternative load-effect, when I expand the root-node?
