JSF: Mojarra 2.1 to 2.2 migration causing ViewExpiredException

Question

I\'m porting my applications from PrimeFaces 3.5.18 + Mojarra 2.1.26 to PrimeFaces 4.0.2 + Mojarra 2.2.4.

When I restart the server I get a ViewExpiredException.

Answer 1

Problem was this: https://java.net/jira/browse/JAVASERVERFACES-2553

Solved it by changing the state saving method to server.
