Problem upgrading to myfaces 1.2 in jbuilder

[Alex Diaz <al...@gmail.com>]

Hi, I am trying to upgrade to myfaces 1.2 in JBuilder (by default 1.1) so  
I can install the richfaces libraries. I copied myfaces libraries to the  
web-inf/lib folder and deleted the older versions from that folder, but  
now when I run the application I get the following error:

javax.faces.application.ViewExpiredException: /pages/inputname.jsfNo saved  
view state could be found for the view identifier: /pages/inputname.jsf

Any ideas how to fix the session state?
Thanks.
