Steps to Reproduce



Log in to the developer environment with any credentials.


Root Cause



A defect in Pegasystems’ code or rules: The affected activity, InitialProfileSetup, was compiled and attempted to reference the Rule-Utility-Function (RUF) isChildRequestor while the owning library was being compiled. As a result, an error was inserted into the compiled code for the activity.

Resolution



Make the following change to the operating environment:

Use the Systems Management Application (SMA) tool to delete the existing VTable entry for the activity InitialProfileSetup.

The next reference to the activity will then correctly generate the compiled code since the RUF is in the library and available.
