Upper case TRUE is working in Pega 6 but not in Pega 7



A user has a When rule in which they used "TRUE = true" as a condition. When this is run it returns false in the Pega 7 series, whereas, in the prior Pega 6.2 version it returned true.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create a When rule with the "TRUE" = "true" condition.
  2. Run the When rule from Designer Studio.
  3. Observe in Pega 7 it returns false.

Root Cause

A defect in Pegasystems’ code or rules. In the Pega 6 series, loose casing of boolean values was not detected; whereas, in the Pega 7 series this was updated to more tightly align to java's handling of boolean values.


Perform the following local-change:
Update all targeted boolean values to the lower case text versions:
