Hi Bob,
First, general questions like these are better asked in the Tech forum. This forum is meant for guides on how to do stuff, not for questions on how to do stuff. The Tech forum also gets much more attention from fellow OutSystems users, so you're more likely to get your questions answered there.
That said, I can't reproduce your error. If I change the Link's Visible property to False, no RichWidgets error appears. Can you share a minimal eSpace that shows your problem?
