Hi,

I am currently developing an application using Symfony.  So far it has
gone reasonable well but I hit a snag today that has me stumped.

I have a form displayed on the screen and I am using the observe_field
() helper to make an ajax call to a function that updates a
calculation and returns the result to a partial to render a new chart.

I've reviewed the manual and the forum and as far as I can tell I am
using the helper right but nothing is happening when the form field is
changed.  I should point out here that I am observing multiple fields
(but not all) of the form.

This is the code:
   <?php echo observe_field('patronage_curve_type', array(
     'url'       => 'patronage/updatechart',
     'update'    => 'dynamic_chart',
     'with'      => "'curve_type=' + value&patronage_id=".$patronage-
>patronage_id
   ))?>

The element 'patronage_curve_type' is located in a partial that is
located before the javascript call in the template.

The following js files are loaded in the template:
 <script type="text/javascript" src="/sfJqueryReloadedPlugin/js/
jquery-1.2.6.min.js"></script>
<script type="text/javascript" src="/js/FusionCharts/
FusionCharts.js"></script>
<script type="text/javascript" src="/sfProtoculousPlugin/js/
prototype.js"></script>

I have
<script type="text/javascript">
//<![CDATA[
jQuery.noConflict();
//]]>
</script>
at the bottom of the page between the </body> and </html> tags (its in
the layout file)

I tried using manual javascript but still no joy in getting the
update.  I checked whether the problem was with the action by using
  echo 'ajax call made"
  break;
at the top of the action and this didn't produce an error message.

My development environment is Windows XP, Eclipse PDT.  I am using
Firefox 3.1 Beta 2 as the browser.

I've run out of things to try.  Does anyone have any idea of what
could be wrong or what I am doing wrong?

Thank you.

Regards,

Simon
