Property-Exist is true for non-existing embedded page property



After upgrading from PRPC 6.2 to Pega 7.2 the Property-Exist function is returning true for properties which do not exist.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create an Activity.
  2. In the first step's precondition, check the value of an embedded page property, that does not exist on clipboard, with a condition.
  3. In the next step's precondition, check the value of the same embedded page property using Property-Exist function.
  4. Observe that the Property-Exist condition evaluates to true.

Root Cause

This behavior of When rules was changed in the Pega 7 series, a When rule will create the property if it does not exist.


Perform the following local-change:

An implementation change is necessary to accommodate the updated behavior.

In this above described scenario for example, if one switched the pre-conditions.order both would report their targeted values.
