  SAP Error Message:
  WD466 Container definition for event '&' not found
  
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when the framework tries to trigger an event on a UI element (like a button, link, etc.), but the event is not defined in the context of the UI element's container or component controller.
  More specifically:  
  
  The event name (represented by '&' in the message) is not found in the container definition of the Web Dynpro component or view.
