Mix-Ins in EMF [message #620752]

I have a class A defined in an .ecore model which implements interface IA,
and an interface IB defined in a second .ecore model

I need to mix the behaviour of the interface IB into class A at runtime.

The usual way would be to create a wrapper class C which implements IA and
IB, wraps the runtime instance of A, and delegates all of its methods
specified by IA to A.

However the EObject classes which access the features of A make frequent
use of the "this" keyword, which means that setting features on C will
fail.

What is the correct way of mixing in behaviour at runtime in EMF?
