I have a rich tree component used by the applciation for navigation.  After the user selects a node of the tree the system navigates away from the page containing the tree.  The user may naviagte to multiple unrelated views.  When the user returns to the view with the tree I am attempting to have the view restore the expanded noeds to the same state it was when the user left that view.

I have tried binding the view to a session scoped bean attribute but this doe snot seem to work wither.

It does seems that the tree component will save its state across requests if using server or ajax switch type but not across the session.

I assume this is a pretty typical use cases.  Does anyone have a suggestion on how this can be accomplished?
