Tree grid view following javascript come during page load

[rajputamit]

I am using Tree gridview

<ext:TreeGrid ID="resourceTree" runat="server" Width="500" Height="600" NoLeafIcon="true"
AutoScroll="true" AutoWidth="true">
</ext:TreeGrid>


following error comes at page load

initColumns : function () {
var cs = this.columns,
len = cs.length,
columns = [],
i, c;

Microsoft JScript runtime error: 'length' is null or not an object
