Antwort: URGENT! HELP ME! Tree2 state problem

[mathias . werlitz]

You could set preserveToggle="false", but this is the general problem that the tree does not "like" dynamic changing tree structures, because the TreeState is not notified of the changes.
I will propose a patch that will make the tree more tolerant to "incompatible" states, see MYFACES-568.
