restoreViewState with HTMLB-TREES/TREENODES

Hello,

we want to achieve that our dynamic tree will

be built up in the state it was before we jumped onto another page. When navigating backwards, the tree

does not remember any more it treenodes properties.

Just the root is displayed, not any more the information which node was open and which not.

Also restoreViewState = "TRUE" did not help.

Any ideas ?

Thanks.
