带有隐藏输入的有序列表

Question

I have such code form in my webapp ( http://jsfiddle.net/eavjd5dd/ ) but when I send a listed item the order is as it was at the default situation.

so my question is why does the new order of the hidden values are not taken in consideration in the server side...? Is there another function to call to apply the ordering of the ordered list...?

Thanks for the help guys :)

<style>
    #sortable{
        -margin-left: 0;
        padding-left: 0.5;
        list-style-type:;
    }
    .ui-state-highlight{
        padding: 2px;
        margin: 2px;
        border: 1px dashed black;
        height: 20px;
    }
</style>
<script>$(function(){
$("#sortable").sortable({axis: "y", placeholder: "ui-state-highlight"});
});

Answer 1

Thanks a lot my friend the collection was the problem. I effectively converted my array of string into an array of long[] and it worked well.
