MVC2 validates model also there are no validation attributes to properties

Question

I've got a model:

public class OverdraftForm
{
    public string CustomerId { get; set; }
    public PaymentType PaymentType { get; set; }

    public OverdraftType Type { get; set; }

    public decimal PermanentAmount { get; set; }
    public int ExpirationPeriod { get; set; }

    public decimal OnetimeAmount { get; set; }
    public DateTime ExpirationDate { get; set; }
    public CreditType CreditType { get; set; }
    public string Comment { get; set; }
}

And my action is

public ActionResult CreateOverdraft(OverdraftForm form)
{
    if (form.Type == OverdraftType.Permanent)
        return CreatePermanentOverdraft(form);
    return CreateOnetimeOverdraft(form);
}

The point is when I debug it, even on the first line of action ModelState.IsValid is false, and it says that OnetimeAmount should have a value. I'm using MVC2, I guess some changes to it cause this problem.

It is a change with MVC2 - on automatic databinding, it's going to read all your properties (even the read-only ones) to try to validate them.

set the Required attribute on the field to false. by default it is true.

Sorry for a stupid question. But how should I do that? [Required(false)] does not (and should not) work – HiveHicks Aug 16 '10 at 14:47

try to make it nullable: public decimal? OnetimeAmount { get; set; } – akonsu Aug 16 '10 at 15:15
