Editable date fields from an XML file...

Hi - excellent datagrid tool. But, as far as I am new in these subjects, I need some assistance:

I'm trying to load an XML file that's structured roughly like this (I named it grid.xml):
<excepciones>
<excepcion>
<desde>15/12/2006</desde>
<hasta>10/10/2005</hasta>
</excepcion>
<excepcion>
<desde>12/12/2003</desde>
<hasta>11/10/2002</hasta>
</excepcion>
</excepciones>

Reading some posted comments, I was able to implement a grid that displays the XML data and gives the chance to edit each cell by providing a calendar control, but after correctly selecting the desired date from the calendar it stops the editing and returns the following script error message:"Line: 24 Char: 8187 Error: Object doesn't support this property or method Code: 0".

My code, thus far, looks like this:
<html>
<head>
<title>Grid :: Test</title>
<style> body, html {margin:0px; padding: 0px; overflow: hidden;} </style>

Please let me know your comments, any help will be very much appreciated. Regards

I figured it out, but I would have really appreciated a lot your comments or advice. Anyway, this was solved by replacing:

obj.setDataText = function(value, i, j){table[i][j] = value};

with:

table.setText = function(value, i, j){
var node = this.getNode(i, j);
node.text = value;
}

I hope this helps anyone else.
