I am not sure if this say anything but it might indicate that the dataview has been changed a little. Try typing this into the javascript editor to gain some insight. I got this from the samples download on msdn. http://msdn.microsoft.com/en-us/library/bb514232(VS.100).aspx">http://msdn.microsoft.com/en-us/library/bb514232(VS.100).aspx

var dv = new Sys.UI.DataView();

when you type dv. the intellisense should give you some more information.

 fetchOperation: "Customers",
 fetchParameters: { $top: 20, $orderby: "FirstName" }

... would be my first guess.
