I have a website which uses a repository for a contacts search.

I have created a partial router so I can have a virtual contact details page available after my contacts search page which is a page in the CMS.

The 'GetRecord' method in repository returns a type of iContact.

public class ContactPartialRouter : IPartialRouter<Models.Pages.ContactsSearchPage, IContactRecord>
    {
        public PartialRouteData GetPartialVirtualPath(IContactRecord content, string language, System.Web.Routing.RouteValueDictionary routeValues, System.Web.Routing.RequestContext requestContext)
        {
            // Get the content link  for the page context.
            var contentLink = ContentRoute.GetValue("node", requestContext, routeValues) as ContentReference;

            if (contentLink == null)
                return null;

            var t = new PartialRouteData
            {
                BasePathRoot = contentLink,
                PartialVirtualPath = content.Username
            };

            return t;
        }

        public object RoutePartial(Models.Pages.ContactsSearchPage content, EPiServer.Web.Routing.Segments.SegmentContext segmentContext)
        {
            // We need to remove the added trailing slash at the end that was added by EPiServer in GetPartialVirtualPath 
            var username = segmentContext.RemainingPath.TrimEnd('/');

            segmentContext.RemainingPath = string.Empty;
            segmentContext.RoutedContentLink = content.ContentLink;

            var repository = ServiceLocator.Current.GetInstance<IContactsRepository>();

            return repository.GetRecord(username);
        }
    }

When I register a template for the interface:

public partial class ContactPage : SimplePage, IRenderTemplate<Business.Interfaces.IContactRecord>  

I am returned a 404 not found error when navigating to a partially routed page.

When I register a template for a concrete instance of the interface:

public partial class ContactPage : SimplePage, IRenderTemplate<ActiveDirectoryContactRecord>

The template is returned with the data correctly.

Do I need to register the template differently to work with the interface? Is this a bug in EPiServer? Should it be possible to-do this?

Thanks,

Adam
