at com.pegarules.generated.activity.ra_action_pzloadstagestatusdp_920dda99c2721a1c865d9b3ff3a75d24.step2_circum0(

Steps to Reproduce

Run a process that includes a section in which the D_CaseStages data page is referenced.

Root Cause

An issue in the custom application code or rules:
A work object is added on page customPage. When the pzLoadStageStatusDP activity is executed, it looks for data on pyWorkPage, which does not exist.


Perform any one of the following local-changes:
  • Use pyWorkPage instead of customPage when adding the work object.
  • Modify the harness so that the pyDisplayStages section is not referenced.
