Viewstate occasionally not restored
-----------------------------------
Key: MYFACES-3000
URL: https://issues.apache.org/jira/browse/MYFACES-3000
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.0.2
Environment: Deployment running under glassfish or Google App engine
but probably happens on all app servers.
Reporter: Werner Punz
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 from
my ajax request from the server:

After that following error request:

And aftert hat I am getting a normal answer again:

As it is visible here the viewstate between the error and the visible request
are the same, it is just that in the first instance it was not able to restore
the view
The error I have gotten on the console is as follows:
javax.faces.application.ViewExpiredException: /welcome.jsfNo saved view state
could be found for the view identifier: /welcome.jsf

So the use encryption param is on default and no key overrides are set!

remove the encryption param there from the web.xml)
