The second form "$(id).update("<p>Hi there</p>"); seems most
appropriate, but my element is a form field, oid of the element $
('eventform'). Firebug shows me that it hasn't processed an update
because it sends my default value of $('eventform').oid to the
server. So I think the $(id) part is the problem: how to address $
('eventform').oid as an element?
