Summary

Users have a validation rule in place with an empty message field. Post upgrade, from PRPC 6.2 SP2 to Pega 7.1.6, '**' (double asterisk) displays instead of nothing on the validated field.

Error Messages

** 

Steps to Reproduce

1. Create a validation rule.
2. Refer a message to display with no message.
3. Observe the behavior at run time.

Root Cause

It is a valid documented behavior of PublicAPI getRuleMessage, of adding '** ' when a message rule is not found.
User has an incorrect configuration that works in PRPC 6.2 SP2 because of a bug. Latest version of PRPC has this bug fixed and the reported behavior manifests post upgrade.

Resolution

Change the edit validate rule to specify a rule message to the message field that has some text in it instead of an empty string.
