Page set messages are not shown in certain flow actions
User is submitting a flow action that contains a drop-down control, which is configured to load its values after the screen renders.
If Page Messages are set, user does not see them displayed, when the flow action is re-displayed.
Steps to Reproduce
- Configure a drop-down list to load its value after the screen renders.
- Submit a flow action that contains this drop-down control.
The root cause of this problem is a defect in Pegasystems’ code/rules that results in the page message being removed.
This issue is resolved through the following local-change in the current version:
Adjust the configuration of the affected dropdown control's load behavior from "After screen renders" to "At screen load (Default)".
The underlying issue is slated to be addressed in a future release of Pega Platform.
