Strongly typed view using SelectList for DropDownList via ViewData: enter mismatch in submit

I am trying to create a form in ASP.NET MVC2 RC 2 that is based on a calendar event object. The object has an eventTypeId, which is System.Int32, which I need to populate with a select list.

Controller to create the initial view:

[WAuthorize]
public ActionResult AddCalendarEvent()
{
    CalendarEventTypesManager calendarEventTypesManager = 
        new CalendarEventTypesManager();

    ViewData["eventTypeId"] = new SelectList(
        calendarEventTypesManager.SelectAll(), "Id", "Type");

    return View();
}

View snippet (with title):

<%@ Page Title="" Language="C#" 
    MasterPageFile="~/Views/Shared/Site.Extranet.master"
    Inherits="System.Web.Mvc.ViewPage<SomeProject.Models.CalendarEvent>" %>

...

<p><%= Html.DropDownList("eventTypeId") %></p>

The result is HTML code:

<p>
<select id="eventTypeId" name="eventTypeId">
    <option value="1">All school activities</option> 
    <option value="2">All school event</option> 
</select>
</p>

POST Receive Controller:

[WAuthorize]
// TODO research some more
[ValidateInput(false)]              
[AcceptVerbs(HttpVerbs.Post)]
[ValidateAntiForgeryToken]
public ActionResult AddCalendarEvent(CalendarEvent newEvent)
{
    ...

(I tried adding [Bind (Exclude="eventTypeId")]the "CalendarEvent newEvent" before the parameter, but it did not change the behavior.)

Problem: when I submit the form, I get an InvalidOperationException:

The ViewData element with the key 'eventTypeId' is of type 'System.Int32', but must be of type 'IEnumerable <SelectListItem>'.
