  The SAP error message BSP_WD001 View controller implementation &1 contains errors: CONTEXT not attached typically occurs in the context of SAP Web Dynpro applications. This error indicates that the view controller implementation has not properly attached a context, which is essential for the Web Dynpro framework to manage the data and UI elements.
  Cause:
  
  Missing Context Node: The view controller may not have a context node defined or attached. Context nodes are essential for data binding in Web Dynpro applications.
  Incorrect Configuration: The context might be incorrectly configured or not properly linked to the view controller.
  Implementation Errors: There may be errors in the implementation of the view controller methods that handle context data.
  Model Binding Issues: If the model is not bound correctly to the view, it can lead to this error.
  
  Solution:
  
  
  Check Context Definition:
  
  Open the Web Dynpro component in the SAP Web Dynpro Workbench.

  Ensure that the context is populated with data before it is used in the view.
  
  
  
  Debugging:
  
  Use the debugging tools available in the SAP environment to step through the code and identify where the context is not being attached.
  Look for any runtime errors or exceptions that might indicate why the context is not available.
  
  
  
  Rebuild the Component:
