Cases roll back due to Commit failure



Cases roll back when the ServiceLevelEvents agent resumes the flow from an assignment. When a dummy assignment is added later in the flow, the cases execute successfully.

Error Messages Caused by trying to calculate the handle of a class whose instances may not be written to the database: Assign-: code: SQLState: Message: 
at com.pegarules.generated.activity.ra_action_resumeflow_791448c90bc318018f58d1da9f2aca95.step7_circum0( ~[?:?]

Steps to Reproduce

  1. Create a flow with a Service Level Agreement (SLA) specified on an assignment.
  2. Configure the SLA rule to resume the flow.
  3. Run the process and wait for the ServiceLevelEvents agent to execute the case.

Root Cause

A When rule is present that referenced the newAssignPage after the assignment is already completed. As a result, the page is created using the class specified on the Pages & Classes tab. An error occurs when this page is saved since it is created with the Assign- as the class.


Perform the following local-change:

Modify the When rule to check if the newAssignPage exists before referencing it. 

Use the following function: @PageExists("newAssignPage").
