Unable to retrieve XForms engine state

I'm using the nightly build from 9-Dec and periodically I get the  
following error condition when using XForms NG:

   XForms error: Unable to retrieve XForms engine state.

It requires a restart of Tomcat to recover and I can't seem to find a  
repeatable pattern which produces the condition.  It happens both on  
the application I'm building as well as the sample forms.  Has anyone  
else seen this, and if so, is there something that I may be doing to  
cause it?

Either:

o Use "client" instead of "session"

or

o Force a page reload (ctrl-shift-R with Firefox, ctrol-F5 with IE) on
your page after restarting Tomcat. You have to make sure you don't do
this on a page that is the result of a POST, or it won't work.
