Hi,

We have recently upgraded our application from PEGA 6.3 to 7.2.

We have an SSO launch from Application1 to our application. Upon SSO launch, an activity is triggered which will create the work object and create screen has to be displayed.

But the create screen is displayed as blank page upon SSO launch. When i checked the logs i could see the below exception. Is there any known issue in PEGA 7 with XML stream rules?

Below is the exception from logs.
