Problems with XML paging - no values in grid

Hi there,

I have one big problem with the XML paging demo. everything works, but I get no readable values in the gird. Sad

No error message, no error in debug in browser.

XML in Controller.php works fine. Here an example:

index.html looks like:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" -->
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />
<title>CompanyName - PageName</title>
<meta http-equiv="Content-Language" content="en-us" /> 
<meta http-equiv="imagetoolbar" content="no" />
<meta name="MSSmartTagsPreventParsing" content="true" /> 
<meta name="description" content="Description" />
<meta name="keywords" content="Keywords" /> 
<meta name="author" content="Enlighten Designs" />

var dsOption= {
	fields :[
		{name : 'PART'  },
		{name : 'CMDESC1'  },
		{name : 'CMDESC2'  }
	],
	recordType : 'object'
}

var colsOption = [
     	{id: 'PART' , header: "PartNo." , width :100  },
     	{id: 'CMDESC1' , header: "Descr1" , width :300  },
   		{id: 'CMDESC2' , header: "Descr2" , width :300  }
       
];

var gridOption={
	debug : true,
	id : grid_demo_id,
	loadUrl : getTestData, //'Controller.php',
	width: "700",  //"100%", // 700,
	height: "500",  //"100%", // 330,
	container : 'gridbox', 
	replaceContainer : true, 
	listenResize : false,
	resizable : false,
	editable : false,
	remoteSort : false,
	allow_gmenu : false,
	allow_freeze : false,
        groupable : false,
	toolbarPosition : 'bottom',
	encoding : 'UTF-8', // Sigma.$encoding(), 
	pageStateBar : null , //'outStateBar',
	dataset : dsOption ,
	columns : colsOption ,
	clickStartEdit : false ,
	defaultRecord : ["1","2","3"],
	pageInfo : { pageSize:50 }
};

var mygrid=new Sigma.Grid( gridOption );
Sigma.Util.onLoad( Sigma.Grid.render(mygrid) );

</script>
