rich:tree nodes colapse

[lobotomy]

I use rich:tree to display tree of checkboxes, where the checkboxes in the parent nodes influence children nodes,I use a4j support to update status of the checkboxes after selection, then I reload the tree. My problem is that after reload all the tree nodes that were expanded before now are colapsed.

Is there any way to keep the state of the rich:tree after the reloads.

I suppose you should use the following attribute of rich:tree:

componentState

false

false

javax.el.ValueExpression (must evaluate to org.ajax4jsf.model.DataComponentState)

It defines EL-binding for a component state for saving or redefinition

So just bind your tree state to a field in a session scoped bean.
