  Error Message
  WD485 Specify the container elements for method '&'
  
  Cause
  This error occurs in Web Dynpro ABAP when a method that requires container elements to be specified is called, but the container elements have not been defined or passed properly.
  In Web Dynpro, UI elements are organized in containers, and certain methods (especially those related to UI element manipulation or event handling) expect you to specify which container elements they should operate on. If you call such a method without specifying the required container elements, the runtime raises this error.
  Common scenarios include:
  
  Calling a method that manipulates UI elements (e.g., IF_WD_COMPONENT_CONTROLLER~WDDOINIT or event handler methods) without specifying the container elements.
  Using methods like GET_CONTAINER_ELEMENT or FIND_ELEMENT without proper parameters.
  Missing or incorrect container element references in the method call.
  
  
  Solution
  
  
  Specify Container Elements Properly:
  
  When calling the method indicated in the error message, ensure you pass the required container elements.
  For example, if the method expects a container element name or reference, provide it explicitly.
  
  
  
  Check Method Signature:
  
  Review the method signature in the Web Dynpro component or interface.
  Identify which parameters correspond to container elements and ensure they are filled correctly.
  
  
  
  Verify UI Element IDs:
  
  Make sure the container element IDs you are passing exist in the view or component.
  Use the Web Dynpro Explorer to check the UI element tree and confirm the element names.
  
  
  
  Debug the Application:
  
  Set breakpoints in the method to check what parameters are being passed.
  Confirm that container elements are not INITIAL or NULL.
  
  
  
  Review Event Handler Assignments:
  
  If the error occurs during event handling, verify that the event handler is correctly assigned to the UI element and that the element is properly referenced.
