Hi,
We are building a new staging environment and recently upgraded from <b>EP 6.0 SP9 to SP16</b> and we have deployed all the webdynpro applications onto this environment and this is the first time we are testing the environment, and I see some of the webdynpro applications are failing, some of them work fine
I am sure this is not a code issue, because these applications are currently running in production
Appreciate any help
Thanks,
Kiran

Check PA_ApplicationView.java line 166.... The code of your PA Application is not compatible with SP16...

Thanks for your response
Let me give you a brief about our situation
Our Dev and QA environments are on SP18 and <b>Production is on SP16</b> and all these applications are transported from Dev to QA and to Production, and we do not have any issues with this code on Production
And the same code is transported to <b>Staging which is on SP16</b> same as production
Is there any reason why this is failing on Staging but not on production?
Thanks
Hi,
at the line 166 in the implementation view of your PA_ApplicationView, just check if you are calling/using value of any object.
we get a null pointer exception in cases when we are trying to get values from objects or contexts/nodes/value attributes whose value has not been assigned yet.
