Thanks Joost! While I'm sorting through that to find out what youre doing
that I am missing, here is a question. When my onAddRow event is throwing
an exception, shouldn't the transaction be rolled back? I would think that
is expected behavior but the transaction is being committed. When I refresh
the page the row is there. Is there a reason that isnt consistent with the
rest of tapestry transactions?
