That sound reasonable and I've just tested your code with a demo ("Table-Cell-
Editor") of the demobrowser and it worked out for me. All I added are the
semicolons at the end of the "return" statements.

As far as I can see there is no bug. It worked out for me and this is also the
way to do it. Can you post a small code snippet? Maybe we can track down the
issue easier this way.
