    • Type: Bug
    • Status: Resolved
    • Priority: Critical
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 1.14.0
    • Component/s: Core Framework
    • Labels:
      None

      Description

      To replicate:

      • Create a Process Group with a Parameter Context bound
      • Create a Processor that references a Parameter
      • Start the Processor
      • Change Parameter to a value that will make the processor invalid
      • Attempt to change the Parameter again

      This will result in a stack trace similar to:
