Steps to Reproduce

  1. Upgrade PRPC 6.1 to Pega 7.2.
  2. Open an agent rule. 
  3. Click any agent whose agent activity contains a parameter. The parameters do not display in Pega 7.2.
  4. Open the XML of the agent rule.
  5. Search for the parameters of the agent activity. The parameters are available.


The agent activity parameter default values were empty because they were set by the user in PRPC 6.1.
