Component stack mismatch exception displays on portal screen



Component stack mismatch exception displays on the portal screen.

Error Messages

Exception caught while evaluating when The reference something--somexyzorg,Inc.- is not valid. Reason: unexpected character ',' at position 36, expected end of name 
RULE-OBJ-WHEN some-class somewhen #20160801T182205.406 GMT: The reference something--somexyzorg,Inc.

Steps to Reproduce

  1. Configure a When rule with @PropertyExist(.pyLabel)
  2. Maintain the value of pyLabel as something--somexyzorg,Inc.
  3. Evaluate the When rule in a rule

Root Cause

A software use or operation error. The value of .pyLabel is equal to  something--somexyzorg,Inc. on the Clipboard. The PropertyExist function is used to find whether a property exists or not on a page. Hence, the value of pylabel is considered as the name of a property as Pega does not allow the usage of special characters to name a property. As a result, the component mismatch exception occurs.


Perform the following local-change:
Use the @PropertyHasValue(.pyLabel) function instead of the @PropertyExists(.pyLabel) function.
