Re: using ajax helper to reload an element

OK, finally getting a chance to look at this again. The biggest
problem I'm having is passing variable information to the element, so
that it can reduce the scope of what's returned and filter based on a
drop down selection.

Here's some code snippets:

http://bin.cakephp.org/view/168041585

Basically, I've gotten it to call the element from within a 'refresh'
view, called by the controller. However, Firebug shows *no* data being
sent in the AJAX POST, so I can't seem to get the data for the form
element that changed. The debug log shows no data for $this->data when
logged from the controller (homes).

The CDATA for the AJAX observer seems to be setup right:
//<![CDATA[
new Form.Element.EventObserver('booksubject', function(element, value)
{new Ajax.Request('/homes/latest_books_refresh', {asynchronous:true,
evalScripts:true, parameters:Form.Element.serialize('booksubject')})})
//]]>

I tried wrapping it in a FORM tag but that didn't help. Any ideas what
might be going on here?

Thanks :)
