Getting IllegalStateException exception when setting
javax.faces.STATE_SAVING_METHOD to "server"
------------------------------------------------------------------------------------------------
Key: MYFACES-610
URL: http://issues.apache.org/jira/browse/MYFACES-610
Project: MyFaces
Type: Bug
Components: General
Versions: 1.1.0
Environment: Tomcat 5.5.9 on Windows XP.
Reporter: Saul Q Yuan
I have an application that works on 1.0.9 but stopped working when upgraded to
1.1.0. I got a blank screen. And console shows the following error:
java.lang.IllegalStateException: Cannot create a session after the
response
has been committed

....
After a few days tweaking & debugging, I changed the value of the following
setting in my web.xml:
javax.faces.STATE_SAVING_METHOD
from "server" to "client",
Now, my app works again.
I think this is a bug.
