  The SAP error message WL101, which states "Binding not defined for container elements & <= &," typically occurs in the context of SAP Web Dynpro or SAP UI5 applications. This error indicates that there is a problem with the data binding configuration for the UI elements in your application. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Binding Definition: The error usually arises when a UI element (like a table, input field, etc.) is trying to bind to a data source that has not been properly defined in the context of the application.
  Incorrect Context Node: The context node that the UI element is trying to bind to may not exist or may not be correctly defined in the component controller or view.
  Data Model Issues: There may be issues with the data model, such as missing attributes or incorrect data types that prevent proper binding.
  Syntax Errors: There could be syntax errors in the binding expressions used in the UI elements.
  
  Solutions:
  
  Check Binding Definitions: Review the binding definitions in your UI elements. Ensure that the context node and attributes you are trying to bind to are correctly defined in the component controller or view.
  Verify Context Nodes: Make sure that the context nodes are correctly created and populated with data. You can do this by checking the data model in the application.
  Inspect Data Types: Ensure that the data types of the attributes in the context match the expected types in the UI elements. Mismatched types can lead to binding issues.
  Debugging: Use debugging tools to trace the execution of your application and identify where the binding is failing. Check the console for any additional error messages that may provide more context.
  Review UI5 Annotations: If you are using SAP UI5, ensure that the annotations in your XML views are correctly defined and that they match the data model.
  Rebuild the Application: Sometimes, simply rebuilding the application or refreshing the data model can resolve binding issues.
