This typically occurs when there is a misconfiguration in the controller's usage or when the controller is incorrectly referenced in the application.

  Solution:
  
  Check Controller Hierarchy: Review the controller hierarchy in your Web Dynpro component. Ensure that no controller is set as a child of itself.
  Correct References: If you find that a controller is incorrectly referencing itself, update the references to point to the correct parent or sibling controllers.
  Review Component Configuration: Go through the Web Dynpro component configuration to ensure that all controllers are correctly defined and that there are no circular dependencies.
