I'm trying to port my tree from Richfaces 3.3 to 4.
I create the tree programmatically, the tree nodes expand/collapse with ajax (toggleType=ajax).
I'm not sure how to substitute the "TreeStateAdvisor" which (in Riachfaces 3.3) gave me a callback to set the expanded state of a node.
I didn't find anything suitable in the Richfaces 4 examples.
Could the Richfaces guys give me a tip on that?
I need to keep track of the expanded state of the nodes, so I can display the same tree after page refresh.
Thanks in advance.
