My guess is that you are registering (module.addCompostes() )
BaseComposite, which lacks the doSomethingElse() implementation
method.
If you don't register that, and in fact, you don't really need it at
all, since you are probably only interested in Base, and you will be
allowed to do queries on Base, although the result might return all
kind of composite types.
