FluentValidation can't do checkboxes???
I'm using FluentValidation to validate input on an MVC form. 

I have a checkbox. 

No matter what I set the validation rule to, it does not validate the checkbox. 

I know validation is working, because I have a dropdownlist that's validating fine on the same page. 

View

    <%: Html.CheckBoxFor(m => m.fullname_required) %>

Model

    [Validator(typeof(CreateFormModelValidator))]
    public class CreateFormModel
    {
        public int? group_id { get; set; }
		
        public IEnumerable<SelectListItem> Groups { get; set; }
		
        [DisplayName("Fullname is required")]
        public bool fullname_required { get; set; }
    }
    public class CreateFormModelValidator : AbstractValidator<CreateFormModel>
    {
        public CreateFormModelValidator()
        {
            RuleFor(x => x.group_id).NotEmpty().NotNull().WithMessage("Please select a group!");
            RuleFor(x => x.fullname_required).NotNull();        
        }
    }

I've tried 

    RuleFor(x => x.fullname_required).NotEmpty();
    RuleFor(x => x.fullname_required).NotNull();
    RuleFor(x => x.fullname_required).NotEqual(false); 

None of which work. I'm going bananas trying to make this work. It's an F***ing checkbox

PS: I've found threads talking about using jQuery instead, but this is using server side validation, not client side.
