[HttpPost]
[Route("{appId}/Contract/Create")]
public ActionResult Create(ContractViewModel vm, string appId)
{
    // ...
    if (!ModelState.IsValid)
    {
       return View("Create", vm);
    }
    // ....
}

If the controller is called the 1st time string appId is perfectly filled with the RouteDictionary value {appId}. But if the ModelState is not valid and the client have to post a second time the parameter string appId is empty. (The RouteValues still contains the correct {appId}, the Form keeps the correct action url.) What am I doing wrong?

How does your view looks like ? – Shyju Jul 23 '16 at 19:39
@Shyju ouch, there is a hidden input name="AppId". Apparently the empty input has a higher priority than the route parameters. Solved. – mlauth Jul 23 '16 at 19:49
