Werner Punz resolved MYFACES-3000.
----------------------------------
Resolution: Invalid
Fix Version/s: 2.0.3-SNAPSHOT
Ok I did another set of testruns, the error is not reproducable anymore with
the default crypto settings. I guess it was a broken local deployment which
triggered it.
I am setting this one to invalid, since GAE seems to run also stable.

> This is a tricky one. I made a small testing app thanks to the commentary of
> a user who wanted to run MyFaces in GAE and caused a condition which
> occasionally occurs, which prevents the ViewState to be found.
> Here is the mechanis. I have a small test app which loads a page. The page
> triggers a jsf.ajax request from time to time with render none, periodically
> but not connected to the session timeout I am getting single error returns
