Ninject multiple modules

I didnt think this would be a problem originally, but as I keep getting exceptions thought I would post here 开发者_开发问答incase im being an idiot...

I have 2 module classes, one sets up NHibernate and one sets up MVC Controllers, now the problem I have is that I have something like below:

public class NHibernateModule : NinjectModule
{
    public override void Load()
    {
        Bind<ISessionManager>().To<SessionManager>();
    }
}

public class ControllerModule : NinjectModule
{
    public override void Load()
    {
        Bind<SomeController>().ToSelf()
                             .WithConstructorArgument("sessionManager", Kernel.Get<ISessionManager>());
    }
}

Whenever I try to use the controller, it just bombs out telling me that its having problems binding the sessionManager argument. I make sure the list has the Nhibernate module in before the Controller module when I create the kernel.

Is there anything immediately stupid in what im doing above?

Assuming:

public class SomeController : Controller
{
    private readonly ISessionManager _sessionManager;
    public HomeController(ISessionManager sessionManager)
    {
        _sessionManager = sessionManager;
    }

    public ActionResult Index()
    {
        return View();
    }
}

The following should be sufficient:

public class NHibernateModule : NinjectModule
{
    public override void Load()
    {
        Bind<ISessionManager>().To<SessionManager>();
    }
}

public class ControllerModule : NinjectModule
{
    public override void Load()
    {
        Bind<SomeController>().ToSelf();
    }
}

and in Global.asax:

public class MvcApplication : NinjectHttpApplication
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default",
            "{controller}/{action}/{id}",
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

    }

    protected override void OnApplicationStarted()
    {
        AreaRegistration.RegisterAllAreas();
        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }

    protected override IKernel CreateKernel()
    {
        var modules = new INinjectModule[]
        {
            new NHibernateModule(),
            new ControllerModule()
        };

        return new StandardKernel(modules);
    }
}
