[Mono-list] MVC 3 error using Get/Post methods for an action with the same name

[Eddy Zavaleta]

Hi,

I'm  facing troubles when I try to run a simple MVC 3 (Razor) CRUD
application. I got the following error when I visit an url which have
Get/Post methods for an action with the same name in the same controller.

System.FormatException: Index (zero based) must be greater than or
equal to zero and less than the size of the argument list.

Here is a sample of what I've got in my app.

public class CategoriesController : Controller
{
        //...

        // GET: /Categories/Create
        public ActionResult Create()
        {
            return View();
        }

        // POST: /Categories/Create
        [HttpPost]
        public ActionResult Create(Category category)
        {
            if (ModelState.IsValid)
            {
                //...
                return RedirectToAction("Index");
            }

            return View(category);
        }

        //...
}
