Property-Ref step failing due to validation errors



The dynamic class referencing functionality data properties to implementation data classes from a framework layer.

In a prior PRPC release a developer added runtime validation on a Property-Ref method that checks the class of a PropertiesRefName and PropertiesRefValue class.  After performing an upgrade to PRPC 7.1.6, this configuration results in an error at runtime.

Error Messages

The following error message was found in the Pega Logfile:

2014-11-06 10:11:10,762 [ WebContainer : 24] [ STANDARD] [ ] ( internal.mgmt.Executable) ERROR  - Exception The reference WorkPage."PageGroup"("index") is not valid. Reason: class '' not compatible with source property class "framework class"

Steps to Reproduce

To reproduce this issue:

Create a Property-Ref property in a specific class, define the source property's page class as a different class.

Root Cause

The root cause of this problem is defect/misconfiguration in the PRPC operating environment. The environment required the rules to be recreated.


This issue is resolved through the following local change:

The developer had to manually delete the Activity that was exhibiting the error, and manually recreate the activity.  This was found to resolve the problem.
