throws: The type arguments for method 'System.Web.Mvc.Html.SelectExtensions.ListBoxFor<TModel,TProperty>(System.Web.Mvc.HtmlHelper<TModel>, System.Linq.Expressions.Expression<System.Func<TModel,TProperty>>, System.Collections.Generic.IEnumerable<System.Web.Mvc.SelectListItem>)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

What is wrong with it? I've tried passing
List<SelectListItem>
and
List<int>
too in various configurations but to no avail.
