Right we have a JIRA issue on that one I believe. Thats not the particular problem being discussed here though. Mihir's problem is that he is not seeing his new data. I believe in your test scenario you were randomly changing your data between requests. While that might simulate a real world scenario, its much more likely that your data will not change between requests. So I think its a bit of an overstatement to say "I can't see that it works at all ..."
Your problem is a bit complicated and you would have the same problem in h:dataTable as well by the way. I think we talked about issuing a warning in your case right? There are other possibilities to consider as well such as a preserveDataModel attribute when you *don't* want to change the data between posts. sean On 4/19/05, Rob Decker <[EMAIL PROTECTED]> wrote: > I get a fatal exception when the data changes and the user clicks a node > that no longer exists so the tree never gets a chance to render the new tree > node.
