Thanks for your replies - removing the html part already did the job,
and there was no need for a more advanced processing. The only
remaining problem so far is that I haven't managed to obtain my
persisted object (it's persisted in the main page), but the component
I get using AJAX doesn't seem to be able to retrieve it. I'll keep on
trying and I'll summarize it in the Wiki once I'm there.
With regard to Howard's last comment: does this mean that we can
expect something like an
<t:ajaxSubmit href="myComponent" div="myDiv" post="true" id="myId"
onsuccess="function..." onerror="function... " errorMessage="RTFM"/>
I already thought of making such a component myself, which would
include the Ajax.Updater javascript above and include a reference to
prototype.js: but I don't know yet how to prevent this javascript and
the prototype ref to be repeated every time I include such an
ajaxSubmit (except by including it separately in the main page). I
probably have to take a look at the Grid component...
BTW do you also plan to AJAX-ify the delegate option, e.g. when you
have a border/layout component, the <t:body/> will be replaced using
AJAX.

Most of that logic will move into the framework pretty much invisibly.
