What causes this issue?

Web Dynpro component &V4& implements Web Dynpro component interfaces
&V2& and &V3&. Both of these contain
A &V1& method with the same name
Or a &V1& event handler with the same name
Or a &V1& event with the same name
Or a &V1& context node with the same name
Or a &V1& free context attribute with the same name (hanging directly on
the root).
This results in a naming conflict in Web Dynpro component &V4&.

System Response

Web Dynpro component &V4& cannot implement Web Dynpro component
interfaces &V2& and &V3& at the same time.

Web Dynpro component &V4&.
