Michael was the one that suggested it to Joost and myself. :) The usage of Observer in base classes might even completely eliminate the need for DB-aware components. After I implemented the initial Model-GUI-Mediator (MGM) in tiOPF I came to realize how handy the Observer really is. Michael helped extend MGM and the benefits become even more. I'm implementing Actions support in fpGUI now and again using the Observer pattern. So far this totally eliminates the need for TBasicActionLink and descendants - reducing the notifications system between action and clients to mere 10-15 lines of code. That's a huge reduction compared to the code in VCL or LCL to do similar functionality. Anyway, this discussion is now totally off-topic. Interface delegation seems to work very nice with Corba Interfaces by the way. No issues found so far.
