History snapshots incomplete



Snapshots from the rule's history for old versions of rules migrated from PRPC 6.3SP1 display without any preconditions and transitions. When expanding the When or Jump portions of step and selecting "Enable conditions before this action" or "Enable conditions after this action" then the conditions are displayed.

Error Messages

Not Applicable

Steps to Reproduce

  1. Open history of an activity rule with Whens or Jumps that have been migrated from PRPC 6.3 SP1.
  2. Open the history snapshot of the rule.

Root Cause

The activity UpgradeonOpen is not called when opening a snapshot. Adding a conditional call to Upgradeonopen activity from DisplayOldVersion ensures the correct properties are set and displays the ruleform in the right state.


This issue is scheduled to be resolved in Pega 7.2.
