[Seaside] General subclassing question with regards tocallbacks...

[Rick Flower]

Thanks for the comment Boris.. In a nutshell all I want to be able to do
is to have a table of names (or whatever) and be able to click anywhere on
that row and have a callback (or block or ??) get rendered that can work
on the 'selected row'..  I've got the code that changes the coloring when
you hover over a row but the callback/block processing is what's getting
me stumped.. Anyway, I'll continue looking at this some more this evening.
Thanks for the insight..
