    ClientDependancy - Javascript Placeholder Null Reference

    While using ClientDependancy in Umbraco, I am getting an error like below in Elmah. It is related to Client Depdency. This error is coming only on a single page Umbraco/Plugins/ExamineInspector/default.aspx. Anyone have any idea?

    System.NullReferenceException: Could not find the placeholder control to render the JavaScript:JavaScriptPlaceHolder

    In /config/ClientDependancy.config look for a line like this one:

    <add name="PlaceHolderProvider" type="ClientDependency.Core.FileRegistration.Providers.PlaceHolderProvider, ClientDependency.Core" javascriptPlaceHolderId="JavaScriptPlaceHolder" cssPlaceHolderId="CssPlaceHolder" />

    Note the JavaScriptPlaceHolder and CssPlaceHolder values. Your ASPX or your Master page must have these placeholders having the IDs with exactly the same values. You may add them somewhere between <head></head> or anywhere you need the bundled javascript and css. This is how you define the placeholders:

    <asp:PlaceHolder runat="server" ID="CssPlaceHolder"></asp:PlaceHolder>
    <asp:PlaceHolder runat="server" ID="JavaScriptPlaceHolder"></asp:PlaceHolder>
