Steps to Reproduce

After upgrading to 7.2.2, try to open a work item that was created prior to upgrading.

Root Cause

A defect in Pegasystems’ code or rules
For older-version reference links, some extra information is needed in Pega 7.2.2. Reference links in work items created in releases prior to Pega 7.2.2 require reinitialization to populate the work items with the missing information.

Resolution

Apply HFix-33936.
