Hello, thank you very much for that hint. Since I want to update the tree as often as possible at every user interaction and I don't want to add a call to updateNotes() at every possible link or button I will try detect wether the rendering was forced by an action on the tree or by something else. Should'nt be a problem since I have the callback functions.
Again, thank you very much I think I got it now :-) Greetings Thomas 2007/11/27, Matej Knopp <[EMAIL PROTECTED]>: > Hi, > > problem is that you rebuild the entire tree in onBeforeRender(). > onBeforeRender is invoked on every render, even when you > expand/collapse a node.
