    Using the following code (as interpreted from the online docs), I receive Server Error in '/' Application. I take out the JavaScript line, and it works fine. Or, if I put the ClientID into the Page Load and write it to Debug, I can retreive the ID fine. Latest version of the Splitter and VS 2008. Any ideas?

    <TelerikWeb:RadSlidingZone ID="OutputPaneSlidingZone" Height="22" DockedPaneId="PaneCompileOutput" SlideDirection="Top" runat="server">

    <TelerikWeb:RadSlidingPane ID="PaneCompileOutput" MinHeight="22" Title="Compile Output" OnClientDocked="Pane_OnChange" OnClientResized="Pane_OnChange" OnClientUndocked="Pane_OnChange" OnClientExpanded="Pane_OnChange" OnClientCollapsed="Pane_OnChange" EnableResize="true" runat="server">

    var slidingZone = $find("<%= OutputPaneSlidingZone.ClientID %>");

     

    Server Error in '/' Application.
