One other cause of this "ViewExpiredException" message is when there is
a failure to serialize the view tree on the previous request. In this
case, an error message gets written to the logs but the page gets
rendered correctly (because serialization of the view occurs *after*
rendering is complete).

Then when a postback occurs, the view tree cannot be restored because it
was never saved in the first place. And whever there is no view tree to
be restored, it always reports "View Expired".

So please check your logs carefully for a message like "Exception while
serializing view state...." or something similar. It may be that the
newer version of orchestra causes slightly different view serialization
behaviour to occur.

If you can't find anything then please enable debug-level logging and
then attach them to an email.
