The model item passed into the dictionary is of type... But I have good type in view

Question

Hello I have a problem when running my app I have an error like this:

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[SR.Models.Incydent]', but this dictionary requires a model item of type 'SR.Models.Incydent'.

I know that it's caused because in view may be bad reference to model. But my action looks like:\

    [HttpGet]
    public ActionResult ZglosIncydent()
    {
        return View();
    }
    [HttpPost]
    public ActionResult ZglosIncydent(Incydent incydent)
    {
        if (ModelState.IsValid)
        {
            incydent.Id = incydent.generateID();
            incydent.DateAdded = DateTime.Now;
            incydent.Status = "NO";
            incydent.Localization = "{52.1234, 53.1234}";
            incydent.Phone = "+48159623478";

            dbIncydent.Incydents.Add(incydent);
            dbIncydent.SaveChanges();

            setFlash("Zgłoszenie Przyjęte", MyController.SUCCESS);

            return RedirectToAction("Index", "Index", new { Area = "SR" });
        }
        return View(incydent);
     }

And in my View:

@model SR.Models.Incydent

@{
    ViewBag.Title = "Zgłoś Incydent";
    Layout = "~/Areas/SR/Views/Shared/_SRLayout.cshtml";
}

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken();
    @Html.ValidationSummary(true);
    <div class="form-group">
        <div class="input-group" style="width: 50%;">
            <label for="Type">Typ Incydentu</label>
            <select class="form-control" id="Type" name="Type" required="required" style="width: 100%">
                <option value="WS">Wypadek Samochodowy</option>
                <option value="P">Pożar</option>
                <option value="Z">Zasłabnięcie</option>
            </select>
        </div>
    </div>
    <div class="form-group">
        <div class="input-group" style="width: 50%;">
            <label for="Description">Opis</label>
            <textarea id="Description" class="form-control" name="Description" required="required" style="resize: none;" rows="5"></textarea>
        </div>
    </div>
    <input type="submit" value="Zgłoś Incydent" class="btn btn-default" />
}

When I saw the error I thought that line with @model cause the problem but it has a proper type. In controller I have second action View which return IENumerable and it's work fine.

Below View and Index action.

        public ActionResult Index()
        {
            return RedirectToAction("Index", "Index", new { Area = "SR" });
        }
        [HttpGet]
        [Authorize(Roles = "Koordynator")]
        public ActionResult View(String Type = "", String Status = "", String Order = "")
        {
            var Incydents = from s in dbIncydent.Incydents select s;
            switch (Order)
            {
                case "id_desc":
                    Incydents = Incydents.OrderByDescending(s => s.Id);
                    break;
                case "id_asc":
                    Incydents = Incydents.OrderBy(s => s.Id);
                    break;
                case "date_desc":
                    Incydents = Incydents.OrderByDescending(s => s.DateAdded);
                    break;
                case "date_asc":
                    Incydents = Incydents.OrderBy(s => s.DateAdded);
                    break;
                case "type_desc":
                    Incydents = Incydents.OrderByDescending(s => s.Type);
                    break;
                case "type_asc":
                    Incydents = Incydents.OrderBy(s => s.Type);
                    break;
                case "status_desc":
                    Incydents = Incydents.OrderByDescending(s => s.Status);
                    break;
                case "status_asc":
                    Incydents = Incydents.OrderBy(s => s.Status);
                    break;
                default:
                    Incydents = Incydents.OrderBy(s => s.DateAdded);
                    break;
            }

            if (Type != "all" && Status != "all")
                Incydents = Incydents.Where(s => s.Status.Contains(Status) && s.Type.Contains(Type));
            else if (Type != "all" && Status == "all")
                Incydents = Incydents.Where(s => s.Type.Contains(Type));
            else if (Type == "all" && Status != "all")
                Incydents = Incydents.Where(s => s.Status.Contains(Status));
            return View(Incydents.ToList());
        }

Change

@using (Html.BeginForm())

to

@using (Html.BeginForm("ActionNameHere", "ControllerNameHere", FormMethod.Post)

So that the form knows where to POST it's data.
