check this attributes
Also check ajaxKeys and ajaxNodeKeys,
Thanks for the hints --
I had a follow up question where I am working on performance optimisation of our rich tree implementation. What is the best way to get at the "Set of all Nodes" of the Tree that are expanded and rendered on the display... I have a tree data set that is huge. but I am now able to controll the rendering of the tree with the below attributes and expose only selective segments of the tree. Now once I have exposed a selective segments of the tree interactively I would like to programmatically acees those set of nodes from the tree that are interactively exposed. I am using the recursiveTreeNodesAdaptor. and I have tried all of the getAjaxKeys and getAjaxNodeKeys methods they all return Null . getRowData only returns the currently selected node only. Would this be possible ?
