Script error with paginated RadGrid in MOSS 2007

[Chris]

Hi,

 I have a script error happening only in a very specific set of circumstances in a webpart in MOSS 2007 SP1 since I upgraded to Q1 2010.

I have an hierarcial Rad Grid that works correctly until the master table requires pagination, then I get a script error part way through the ajax request and the page hangs and does not recover.

The error is as below:

The line in the js file that causes the problem is :

if(this._disposeChildElements){$telerik.disposeElement(c);

This was all working correctly with the previous version that I was using (2009.2.826.20). As a note the child grids needing pagination does not cause an error only the master table. Please see below for the code for the contol.
