Treeview with "nodeChecked undefned" error

[Greg]

folks
My company has paid for a 3 license copy of KendoUI
I am posting here and not under the company registered user name as no one monitors that email

I am using

2012.2.710 release (because I can't upgrade

I am getting an error when the treeview is rendered.
There error is(see attachment for screen shot):

Unhandled exception at line 8, column 374994 in http://localhost:3407/Scripts/KendoUI/kendo.web.min.js

0x800a138f - Microsoft JScript runtime error: 'f[...].uid' is null or not an object

Browser is IE8. Must use this version : 1.4 billion(and counting) Chinese can't be wrong!!

Here is the Treeview code:

@

 

using DnB.Connect.Mvc.Common.BaseTypes;

 

@

 

using DnB.ConnectEntityModel;

 

@model DnB.Connect.Mvc.Common.BaseTypes.

 

CategoryEdit

script type="text/javascript">

 

 

 

function nodeChecked(e) {

 

 

 

//remember whether e is checked

 

 

 

var isChecked = e.checked;

 

 

 

//select all items

 

 

 

var allCheckboxes = $('#CategoryTreeView').find("li").find('> div > .t-checkbox :checkbox:checked')

 

 

 

//alert('after find');

 

 

 

//remove all checks

 

$.each(allCheckboxes,

 

function (index, checkbox) {

 

$(checkbox).attr(

 

'checked', false);

 

});

 

 

//alert('after check removal');

 

 

 

//put e back as you found it

 

e.checked = isChecked;

 

 

var catDesc = '';

 

 

 

var catId = 0;

 

 

 

if (isChecked) {

 

catDesc = $($(e.item)[0]).find(

 

'span.t-in')[0].innerHTML;

 

catDesc = catDesc.replace(

 

/&amp;/g, '&');

 

catId = $($(e.item)[0]).find(

 

'input[name="itemValue"]')[0].value;

 

$(

 

'#CategoryID').val(catId);

 

$(

 

'#CategoryName').val(catDesc);

 

}

 

 

var span = $("#CatError").remove();

 

}
