"Value cannot be blank" error when executing move rules



Using the Application Explorer, to move rules for a given entity, when the move rules screen is presented a user can select a class and ruleset but the version is blank and a version cannot be selected. 

Error Messages

Version: "Value cannot be blank"

Steps to Reproduce

  1. Designer Studio > App Explorer > (right click on a class) > Refactor > Move Rules.
  2. On the newly presented screen, select a class and ruleset but the user is unable to select version, which is mandatory. 

Root Cause

A defect in Pegasystems’ code. A change was made to the custom control to dropdown and gave report definition as the source to the dropdown which retrieves the version ID based on selected rule set.
