JSF1054: (Phase ID: RENDER_RESPONSE 6 Exception thrown during phase execution

[Ling Lin]

Thank you all who came in and help

I'm trying to solve this JSF related issue but I'm totally new to JSF. I did quite a bit search but I'm still clueless...

Environment:
Websphere 7
JSF 1.2
JSF (IBM Compatibility) 7.0
JSF (IBM Enhanced) 7.0

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:

Could anyone provide a little thoughts?

Any help is appreciated! THANK YOU!

Hi Ling, welcome to JavaRanch!

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.
