This seems bad.  I see a couple of approaches to dealing with this
that would make sense, though:

- Don't be silent, raise an exception.  This lets it be known that
there's a bug in the configuration.

- Use a CustomWidgetFactory that calls the function and then sets the
attributes on the resulting widgets.

I prefer the second option myself.
