3.0 beta 2

kind of footer implementation (paging issue)

I was looking for the solution to implement footer in AW version 1. Finally, I decided to implement it in the next way:
1) initially footer is the last row in the data array
2) copy last row (footer) into new array
2) on sort remove last row and sort the data
3) add new row (copy from footer array)
4) refresh grid

An example you can find bellow:
<html>
<head>
    <link href="../../runtime/styles/xp/grid.css" rel="stylesheet" type="text/css" ></link>
    <script src="../../runtime/lib/grid.js"></script>
    <script src="../../patches/paging1.js"></script>
    <style>
        .active-controls-grid {height: 100%; border: 1px solid #ccc; font: menu;}
    </style>

    <script>
  var myColumns = [
"Date","MAILFROM","RCPTTO","REJECTED","COUNT","SIZE"
];

var myData = [

It works good enough, but only without paging patch. As soon as I add paging functionality, the code doesn't work any more. I spent 3 days and haven't found any solutions. I guess this issue is due to the "reload/change data after sort" bug but I don't think I have any ideas how to fix it.

Any help/suggestions will be very much appreciated.

Thanks in advance
