When I use my test app shortly after deploying or when dormant for
awhile, myfaces throws javax.faces.application.ViewExpiredException.
Specifically, this happens when I use the browser's Back button. After
awhile, it stops happening. It happens with both client & server state
saving. Sessions are enabled in my appengine.xml.
