I would like to use a custom render for a Content Reference Property (PageLink). Here is an example of the custom renderer:

[TemplateDescriptor(TagString = "MyCustomRenderer")]
public class PropertyPageReferenceCustomControl : PropertyPageReferenceControl, IRenderTemplate<ContentReference>
{
	public override void CreateDefaultControls()
	{
		base.CreateDefaultControls();

	// I need todo some stuff here but this template is never rendered.

	}
}

And how I am calling it from a control

<EPiServer:Property ID="Property1" PropertyName="PageLink" runat="server">
    <RenderSettings Tag="MyCustomRenderer" />
</EPiServer:Property>

I want to be able to manipulate the way the PageLink is rendered but with the above, my custom renderer is simple not used.

I have other custom renders working in the same project but for different types. i.e

[TemplateDescriptor(TagString = "UrlWithTitle")]
public class PropertyUrlWithTitleControl : PropertyUrlControl, IRenderTemplate<Url>

Can anyone see what I am doing wrong with the PropertyPageReferenceControl custom renderer?
