ExplorerTree NullReferenceException using sample code

Hi, Could someone point me in the correct direction to understanding why the following is happening and how to avoid it please? I'm writing an Admin plug-in and would like to add an ExplorerTree control. I copied the example from Developing Solutions with EPiServer, modifying it as I assume that there is no CurrentPage so I need to sort out my own PageReference instance for the Pagelink property: I also tried: PageLink="<%# new episerver.core.pagereference(35)%>" and setting the PageLink just before DataBind in the code-behind file. All of which give me the same error: [NullReferenceException: Object reference not set to an instance of an object.] EPiServer.WebControls.PageTreeData.PopulatePages(PageDataCollection pages) +250 EPiServer.WebControls.PageControlBase.ᐁ() +44 EPiServer.WebControls.ExplorerTree.Render(HtmlTextWriter output) +51 Also tried setting PageLink in the code behind file to no success. Does anyone have a working sample of using ExplorerTree that would function correctly in an Admin plugin? I'm using ASP.NET 1.1, EPiServer 4.60 on XP. Cheers, Andy
