Check out the object publishing chapter of the developer's guide

The reason that your example doesn't work is that you are calling the
external method, not using getattr, getitem, or __bobo_traverse__ to
traverse over it. When you call an object you are publishing it, not
traversing over it. In short, you can't traverse over the results of an
External Method.
