For Each Embedded Page option not working

SA-15899

Summary



Using the For Each Embedded Page option in the Steps tab of the Activity form does not save the activity even when the users provided a list or a group property as a step reference. This seems to be a regression from Pega 7.1.8, the previous release in which this problem did not occur.


Error Messages


Invalid expression or reference: When used with a "For Each Embedded Page" option, the Step page should reference a list or group property

Root Cause


An issue in the custom application codes or rules
Defining page name in the Pages & Classes tab of the activity is mandatory starting with Pega 7.1.9.

Resolution



Perform the following local-change:
  1. Define pyWorkPage in Pages & Classes. 
  2. Use property.pxResults and define the same in Pages & Classes.

Note: In the Property-Set method, do not use a target property on which a declare expression has already been defined.
See the Pega 7.1.9 Help topic, Activity form -- Completing the Steps tab - Iteration.
