Property-Ref step failing due to validation errors

SA-3407

Summary



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.
