Rails - Apr 2006 - Trigger ajax form submission with drop_receiving_element

Hello everyone!

I have a little problem with ruby on rails and ajax.

I have 2 sort of droppable items, 2 drop_receiving_element areas working 
fine; but instead of updating a div, I would like to have a form 
submitted with an ajax call. got it? (not so easy to explain)

My solution was to add a complete action submitting the form like this:

<%= drop_receiving_element "list",
      :url => { :action => "add" },
      :accept => "categories",
      :loading => "Element.show(''indicator'')",
      :complete => "new Ajax.Updater(''list'',
''/review/refresh'',
{asynchronous:true, evalScripts:true, 
parameters:Form.serialize(document.listform)});Element.hide(''indicator'')"%>

the action ''add'' add my element to the list, my
''listform'' form is
refreshed by submitting the form through the ''/review/refresh''
action.

it works well like this but, this make 2 ajax calls (''add'' and
''/review/refresh'') and the indicator disappear at the end of
the first
action, not the second action.

How to do with one ajax call / in a cleaner way?

In my program, the user ''build'' a custom form using
drag-and-drop.
If the user begins to fill the form and after add an element, if I
don''t
save the content of the form, the form is resetted.

If you didn''t catch what I mean, don''t hesitate to ask me more
informations.

Thanks for your help,
Maxime.
