at com.pega.pegarules.session.internal.authorization.access.AccessEvaluator.haveAccess(
at com.pega.pegarules.session.internal.authorization.Authorization.haveAccess(


Steps to Reproduce

1) Create a flow in which a Assignment and a sub-process exists.
2) Subprocess has multiple assignment shapes.
3) In perform Harness, include pxDisplayStages section.
4) Include the same section pxDisplayStages in Flow Action of a section.
5) After running the flow in the case, find the exception logged in PEGA_RULES logs.

Root Cause

Issue in the pzStageProcessLink control where Pega internally does security check even when assignment is not there.

This causes the Access_Open error.


Apply HFix-31379.
