Reproducing a bug
Create new ASP.Net MVC application:
Create an action that take non nullable argument called 'id':
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
ViewData["Title"] = "Home Page";
ViewData["Message"] = "Welcome to ASP.NET MVC!";
return View();
}
public ActionResult Test(int id)
{
return Content(id.ToString());
}
public ActionResult About()
{
ViewData["Title"] = "About Page";
return View();
}
}
Go to home/index.aspx and add the following before the final </asp:Content> tag:
<% using(Html.BeginForm("Test","Home")){ %>
<%=Html.Hidden("id",2) %>
<input type="submit" value="test" />
<%} %>
Visit the site and see that you indeed have a test button on the page. Click the button.
Get an exception:
I am going to assume this is a bug.
This is on the ASP.Net MVC beta bits.
