Client is seeing a lot of the following exceptions in their production server log since we upgraded to WAS7 and JSF1.2 but we haven't been able to reproduce this in dev or testing (probably because the volumn is much smaller). Everything worked perfectly fine in testing and production before the upgrade:
I'd guess getSessionModel() returns null. That's a method you implemented, right? That means it's nothing to do with JSF. However, if you want to post the code for that method, we might be able to figure out why it's returning null.
