• What is the cause and solution for SAP error message SO2_TAGLIB025 - Generic types like &1 are not supported ?

  The SAP error message SO2_TAGLIB025 indicates that a generic type is being used in a context where it is not supported. This typically occurs in the context of SAP Web Dynpro or SAP UI5 applications, where certain types of data binding or component usage may not accept generic types.
  Cause:
  
  Generic Types: The error arises when a generic type (like List<T>, Map<K,V>, etc.) is used in a place where the framework expects a specific type. For example, if you are trying to bind a UI element to a generic collection, the framework may not be able to resolve the type correctly.
  Data Binding Issues: The error can also occur if the data binding is not set up correctly, or if the data model does not match the expected structure.
  Framework Limitations: Some versions of SAP's frameworks may have limitations regarding the use of generics, leading to this error.
  
  Solution:
  
  Use Specific Types: Instead of using generic types, define and use specific types that the framework can recognize. For example, if you are using a list, specify the exact type of objects it contains.
  Check Data Model: Ensure that the data model you are using is correctly defined and matches the expected structure of the UI components. If you are using a custom data model, verify that it is implemented correctly.
  Update Framework: If you are using an older version of SAP UI5 or Web Dynpro, consider updating to a newer version where such limitations may have been addressed.
  Debugging: Use debugging tools to trace where the error is occurring. Check the data being passed to the UI components and ensure it is in the expected format.
  Consult Documentation: Refer to the official SAP documentation for the specific framework you are using to understand the limitations and best practices regarding data types and binding.
