AfterClientCallBackError - JS Function was not called

[randz]

I am having a problem with the AfterClientCallBackError. I expect my function to get executed after a callback error was raised but my function was not called, and a default javascript error message was shown instead. (I am seeing something like "UnAuthorized[]_$$_") in the javascript alert. Are there any other event(s) that I can subscribe to to handle the callback error?

I am using Telerik.Web.UI (2008.1.619.20). The AfterClientCallBackError function was defined like this:

function AfterClientCallBackError(node)
{
   alert("The error occured when you tried to expand the " + node.Text + " node");
}

The nodes' ExpandMode were set to ServerSideCallBack and I already tried putting the function before and after the treeview markup but both had the same problem.

<telerik:RadTreeView ID="_uscRadTrvtAuthority" runat="server" AfterClientCallBackError ="AfterClientCallBackError" OnClientContextMenuShowing="ClientContextMenuShowing" EnableDragAndDrop="true" AllowNodeEditing="true" OnNodeEdit="_uscRadTrvtAuthority_NodeEdit" Skin="Web20" ShowLineImages="False" CssClass="RadTreeView" OnClientNodeEditing="OnClientNodeEditing_uscRadTrvtAuthority" OnClientContextMenuItemClicking='OnClientContextMenuItemClicking'>

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="ContextMenu1">

<Items/>

</telerik:RadTreeViewContextMenu>

</ContextMenus>

<CollapseAnimation Type="OutQuint" Duration="100"></CollapseAnimation>

<ExpandAnimation Duration="100"></ExpandAnimation>

</telerik:RadTreeView>

Please help.

Never mind. I figured it out. I subscribed to OnClientNodePopulateFailed event instead.
