Rails - Apr 2006 - RJS across iframes

I have an inline iframe which has a form in it, when the form is 
updated, I would like to call an RJS template that will update the 
parent page.

+-----------------------------------------------+
|                                               |
| <div id="mydiv"> Update with RJS </div>       |
|                                               |
|  +---------------------------------+          |
|  | <iframe> with form that when    |          |
|  | update will call RJS teplate to |          |
|  | update "mydiv"                  |          |
|  +---------------------------------+          |
+-----------------------------------------------+

If in the controller I can pass the RJS template the parent page rather 
than the iframe''s page which will be the default for any action that 
renders the iframe...

Anybody got any suggestions...

Thanks,
James

If anybody has a clean way to do this, would be interested. But 
otherwise have solved it by coding native javascript :(

FYI this was to create an inline image uploader as you can''t do this 
with ajax so I embedded an iframe and wrapped it with javascript to 
emulate ajax.

On the iframe;

javascript_tag( 
"window.parent.myFunctionOnTheParentWindow(\''#{@object.id}\'')")

and then on the parent form;

function myFunctionOnTheParentWindow(object_it) {

if (photo_id) {
	new Ajax.Updater(''photo_items'',
''/admin/photo_show'',
		{asynchronous:true, evalScripts:true,
			 insertion:Insertion.Bottom, 
onComplete:function(request){Element.hide("photo_upload_saving"); new 
Effect.Highlight(''photo_box_'' + photo.id);}, 
onLoading:function(request){Effect.BlindUp("photo_new")},
			 parameters: "id=" + photo_id});
	}

}

works perfectly.
