在我的MVC4应用程序中，我使用的是MVC FoolProof库
在我的元数据类中，我有
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; }
}
但是在我的控制器post方法中，db.SaveChanges
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(R_Deals r_deals)
{
if (ModelState.IsValid)
{
db.R_Deals.Add(r_deals);
db.SaveChanges();
}
}
以下是例外的详细信息
An unexpected exception was thrown during validation of 'PointEarnType' when invoking Foolproof.RequiredIfAttribute.IsValid. See the inner exception for details.

在这种情况下我该怎么办？实际上并没有出现我的错误。
请帮帮我！谢谢
