[Seaside] Using updater without triggering action callback?

[Boris Popov]

Say you have a form with default action callback to run a search. One of
the criteria for this search is specified using a select list in that
form. Now I'd like to attach an updater to the select list to populate a
little "extras" div to the side of it with selection details, but I
would like to do so without triggering the default action of a form that
would actually execute the search?

(html select)
 list: self accounts;
 labels: [:acc | acc name];
 selected: self account;
 callback: [:value | self account: value];
 onChange: ((html updater)
                id: divid;
                triggerForm: formid;
                callback: [:r | r span: self account name])
(html div)
  id: divid;
  with: [].

Thanks,

-Boris
