Hi Team,
In Pega Constellation 25.1.1, I have a requirement to trigger logic when a case is opened. I have configured this logic in an OpenDefaults extension rule.

Issue:

• When I open the case in the Dev Studio / Dev Portal, the OpenDefaults rule triggers as expected.
• However, when I open the same case in the User Portal, the OpenDefaults rule does not trigger.
• I have traced the execution and confirmed that the OpenDefaults rule is not being invoked in the User Portal.

Is this expected behavior in Constellation (25.1.1) applications?
Are there any known limitations, differences in lifecycle handling, or root causes for OpenDefaults rules not triggering in the User Portal?
