Steps to Reproduce

Not Available

Root Cause

An issue in the custom application code or rules.

Custom activity is calling for logging off and it is not enabling the parentWindow.logout to true in
pzpega_ui_doc_lifecycle.js, which will call the pyDeleteDocumentPg activity and causes the issue.


Perform the following local-change:

Designing the custom log out activity in a way that it will call the custom code and the Out-of-the-box (OOTB) logoff activity in custom java script file which will resolve the issue.
