Unless you are well versed with interfaces, I would not go there. Mixing
object references and interface references (especially if reference
counting is enabled) - you
You're original problem is exactly why I said mixing class instances and
interface instance is looking for trouble. You better know what you are
doing.
Attached are two examples of your program. One using CORBA interfaces,
the other using non-reference counting COM style interface. Both work
