Re: How do I get a change in my tree model to be displayed?
Hi, first of all, in the first line of the loop, shouldn't node be nextNode? Then, you're directly calling listener methods, which are supposed to be callbacks, i.e., they are called by the framework when, and after, a selection or expansion happens. You should use the methods offered by ITreeState, such as expandNode(node) (as you do with selectNode). Your listener methods will be called, if you added your listener to the tree.

How do I get a change in my tree model to be displayed?
Hi. The ajax stuff is a bit new to me, so sorry if this is an obvious question. I'm trying to figure out how to get my change in my tree model to show up on screen. I want to be able to expand to and select a node from the tree based on its value (determined elsewhere in the application). I resolve the path of the node I want, grab any not-yet-resolved children from the DB (my tree is large, so I only fetch my children as required), and then I expand and select. final ITreeState treeState = getTreeState(); final TreeNode[] path = node.getPath(); for( final TreeNode nextNode : path ) { treeState.selectNode( node, true ); nodeExpanded( nextNode ); nodeSelected( nextNode ); } invalidateAll(); Maybe I do some unnecessary stuff above, I don't know. In any case, after expanding and selecting the node in my model, the big thing for me is to get that change to take effect. Thanks for the help!
