[jQuery] Firefox Error (bug?) with Sortable

[PeteShaw]

Hi,

I've searched around a bit and can't find any examples of someone
having the same issue, so hopefully someone out there can help. I'm
try to save sort order server side through a ajax call on sortable
stop.

I've got this to work in IE6/7 using the stop: event to call a
function i.e.:

var sortingOptions = { opacity: .5, containment: "parent", items:
".item", stop: function(e) { OnSorted(e) } };
$(".toolBelt.sortable").sortable(sortingOptions);

which calls another js:
void function OnSorted(InE) {
   //On Drop of Drag Drop sort

   var ButtonList;

   ButtonList = InE.target.parentNode.parentNode.parentNode.all;
   var i;
   var query_string = "";
   //loop through and create querystring from array
   for (i = 0; i <= ButtonList.length-1; i++) {
       if (ButtonList[i].id!="")
           query_string += ButtonList[i].id + ",";
   }

   $.ajax(
   {
       type: "POST",
       url: "/Pages/ajaxPostBack.aspx",
       data: "postback=EditApp;" + query_string
   });

However if I try the same operation in Firefox 3 I get the javascript
error:
OnSorted is not defined
[Break on this error] var sortingOptions = { opacity: .5, containment:
"parent", items...

Anyone come across this before?

cheers

Pete
