Thanks Eelco, I'll check it out. It looks like it uses reflection and
lots of default values to allow editing for every single attribute in a
bean. Is that right?
How's JavaOne?

Did you take a look at the code I put in wicket-example's HEAD, the
wizard example? There is some bean editing stuff in there that does
things on a whole different way than you propose. Maybe it is a good
idea to check this out, and see what you do and don't like, and have a
discussion on that.
