Changing dataProvider of custom dataGrid to XCelsius Cells

Question

Hi everybody,
I have quite a simple question, however, I do not really get a solution for that on my own.
Actually, all I want to do is extend a usual Datagrid to display my data from XCelsius using the standard propertysheet. The way I tried to do this was to make the dataProvider inspectable.
My actionscript file:
package myPackage
     import mx.controls.DataGrid;
     [CxInspectableList("dataProvider")]
     public class MyDG extends DataGrid
          public function MyDG()
               super();
          [Inspectable(defaultValue="undefined", type="Array2D")]
        [ArrayElementType("Number")]
          override public function get dataProvider():Object
               return super.dataProvider;
          override public function set dataProvider(value:Object):void
               super.dataProvider(value);
When I pack this into an .xlx, I can view it and preview it as long as I do not try to change the dataProvider. When changing it, the preview window stops to load at some point.
Thanks for your help in advance!

Hi Sreelekha,
This is how Flex creates 2d arrays so Xcelsius does the same when it passes a 2d array.
var cells:Array =
   /* row 1 */   [ column 1, column 2, column 3],
   /* row 2 */   [ column 1, column 2, column 3],
   /* row 3 */   [ column 1, column 2, column 3]
So in your case:
var cells:Array =
    [P1, C1],
    [P2, C2]
So cells.length tells you how many rows are in the 2d array.
And cells[0].length tells you how many columns are in the first row of the array (assuming there is at least one row).
So as in Flex if you want to process a Flex 2d array you do something like this:
for (var i:int = 0; i < cells.length; i++)
    var row:Array = cells<i> as Array;
    for (var j:int = 0; j < row.length; j++)
       var rowColCell:* = row[j];
       // rowColCell has the value for this row/column cell.
