System.NotImplementedException : "The method or operation is not implemented." FoolProofValidation

Question

In my MVC4 application I'm using MVC FoolProof library

In my Metadata class I have

public class R_DealsMetaData
{
    public int ID { get; set; }
    public int UserId { get; set; }
    public bool CodeGenerated { get; set; }

    [Required(ErrorMessage="Please Enter Description")]
    [Display(Name="Promotion Name:")]
    public string Description { get; set; }

    [Required(ErrorMessage = "Please select one Option")]
    [Display(Name = "Deal Buy:")]
    public int Buy { get; set; }

    [Required(ErrorMessage = "Please select one Option")]
    [Display(Name = "Deal Free:")]
    public int Free { get; set; }

    public Nullable<bool> Status { get; set; }

    public string Type { get; set; }

    [DataType(DataType.Date)]
    public System.DateTime CreateDate { get; set; }

    [DataType(DataType.Date)]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
    [Required(ErrorMessage = "Please select Expiry Date")]
    [Display(Name = "Promotion Expiry Date:")]
    public System.DateTime ExpiryDate { get; set; }

    [RequiredIf("Type", "P", ErrorMessage = "Please select")]
    public Nullable<int> PointEarnType { get; set; }

    [RequiredIf("PointEarnType", 2, ErrorMessage = "Please enter value")]
    public string PointEarnMealText { get; set; }

    [RequiredIf("Type","V",ErrorMessage="Please enter")]
    public string VolumeBuyText { get; set; }

    [RequiredIf("Type","V",ErrorMessage="Please enter")]
    public string VolumeEarnText { get; set; }

}

But at my controller post method an exception has been thrown on db.SaveChanges

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(R_Deals r_deals)
    {
        if (ModelState.IsValid)
        {
            db.R_Deals.Add(r_deals);
            db.SaveChanges();
        }
    }

Following are the details of exception

An unexpected exception was thrown during validation of 'PointEarnType' when invoking     Foolproof.RequiredIfAttribute.IsValid. See the inner exception for details.

What should I do in this case? Not getting actually where I am going wrong .

Please Help me! Thanks

Foolproof Validation has problems with EntityFramework. For more details see this bug report
