  SAP Error Message:
  WD063 Reference of container element '&' was changed -> see long text
  
  
  Cause:
  This error occurs in Web Dynpro applications when the reference of a container element (UI element or context node) is changed unexpectedly during the runtime. In Web Dynpro, container elements (like UI elements or context nodes) are expected to maintain their references during the lifecycle of the application. If the reference changes, it usually indicates that the element was replaced or re-initialized improperly, which can lead to inconsistencies in the UI or context handling.
  Common causes include:
  
  Replacing or re-creating UI elements or context nodes dynamically without proper handling.
  Incorrect manipulation of context nodes or UI elements in the component controller or view controller.
  Using methods that reset or clear the container element reference unintentionally.
  Issues in the lifecycle management of the Web Dynpro component/view.
