Hello.

I have the following controller and action:

public class RegisterController : SurfaceController
{
    private readonly IViewRenderService viewRenderService;
    private readonly UmbracoHelper umbracoHelper;
    private readonly SignInManager<DBUser> signInManager;
    private readonly UserManager<DBUser> userManager;
    private readonly IMapper mapper;
    private readonly DBContext context;

    public RegisterController(IUmbracoContextAccessor umbracoContextAccessor,
                          IUmbracoDatabaseFactory databaseFactory,
                          ServiceContext services,
                          AppCaches appCaches,
                          IProfilingLogger profilingLogger,
                          IPublishedUrlProvider publishedUrlProvider,
                          IViewRenderService viewRenderService,
                          UmbracoHelper umbracoHelper,
                          SignInManager<DBUser> signInManager,
                          UserManager<DBUser> userManager,
                          IMapper mapper,
                          DBContext context) : base(umbracoContextAccessor, databaseFactory, services, appCaches, profilingLogger, publishedUrlProvider)
    {
        this.viewRenderService = viewRenderService;
        this.umbracoHelper = umbracoHelper;
        this.signInManager = signInManager;
        this.userManager = userManager;
        this.mapper = mapper;
        this.context = context;
    }

    [HttpPost]
    public IActionResult Finish(FinishRegistrationFormModel formModel)
    {
        var a = CurrentPage;
        return new EmptyResult();
    }
}

When I post to the action from a standard HTML form it results in the following exception on the CurrentPage line:

System.InvalidOperationException: 'No UmbracoRouteValues feature was found in the HttpContext'

I'm pretty sure this is a bug, but don't know if I should have opened an issue on github. Should I, or only contributors can?

I also have a sugestion. Currently the Index() method of RenderController (used to perform the route hijacks) does not allow being async which is quite a big limitation in my opinion. Or am I missing something?

Thanks
