[jira] Created: (MYFACES-3000) Viewstate occasionally not restored
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:
Working Request before:

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:

[jira] Commented: (MYFACES-3000) Viewstate occasionally not
restored

Werner Punz commented on MYFACES-3000:
--------------------------------------
Ok I am still trying to reproduce the error here locally with default settings, I am not entirely sure if the error was not caused by a broken config which might have carried over by a broken deployment.
So please do not do anything on this issue until I come to a clear conclusion.

[jira] Resolved: (MYFACES-3000) Viewstate occasionally not restored
Posted by "Werner Punz (JIRA)" <de...@myfaces.apache.org>.
[ https://issues.apache.org/jira/browse/MYFACES-3000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
