[jQuery] sortable update problem

[jQuery] sortable update problem


I am using sortable and using the update feature to post the order
$("#2").sortable({
        //connectWith: ["#homePage","#acquire","#build"],
        items: "li",
        opacity: "90",
        revert: true,
        placeholder: "sortHelper",
        activeclass: "sortActive",
        hoverclass: "sortHelper",
        dropOnEmpty:true,
        update: function(element, ui) {
             $.post("addLinks.php",{ step:'update',order:$(this).sortable
("serialize")});
}
});
it seems that update doesnt work after i upgraded to jquery 1.3.1
i also upgraded jquery ui to
1.5.3 as well as sortable
I can drag and drop and do everything I used to be able to do with
1.2.6. I upgraded to take advantage of the new live function for event
delegation
What could of changed or what I am i missing to make update work
Thanks
Tom
