Basic approach:
- Create your API reference (your CreateObjectEx call should work fine for
that).
- Get a walker (your controlViewWalker call should do that).
- Set walker.currentElement to an object, like api.getFocusedElement().
- Navigate using the .goto*() calls, which return boolean True on success and
False on failure.
- Use walker.currentElement to access the final destination.

Soronel,
I tried it with CreateTreeWalker and the true condition with the same result.
The clue here. I think, is that after using either TreeWalker approach, the use
of the GoTo methods always return false. I can't resolve that basic problem.

Make sure that CurrentElement is actually set to something before you do the
series of GoTo calls. I don't know about ControlViewWalker but I do know that
when usingCreateTreeWalker with a true condition to enumerate everythign that
CurrentElement starts out null
