遠程驗證MVC 4.0：多個字段驗證不明確的錯誤

我有以下視圖模型：遠程驗證MVC 4.0：多個字段驗證不明確的錯誤

public class EmployeeVM : IEntity 
{ 
    [Remote("ValidateUniqueFullName", "Employee", AdditionalFields = "LastName,Id")] 
    public string First { get; set; } 

    [Remote("ValidateUniqueFullName", "Employee", AdditionalFields = "First,Id")] 
    public string LastName { get; set; } 
}

的看法是這樣的：

<tr> 
    <td> 
     @Html.LabelFor(model => model.First) 
    </td> 
    <td> 
     @Html.TextBoxFor(model => model.First) 
    </td> 
    <td> 
     @Html.ValidationMessageFor(model => model.First)    
    </td> 
</tr> 
<tr> 
    <td> 
     @Html.LabelFor(model => model.LastName) 
    </td> 
    <td> 
     @Html.TextBoxFor(model => model.LastName) 
    </td> 
    <td> 
     @Html.ValidationMessageFor(model => model.LastName) 
    </td> 
</tr>

當你只在名字填寫，你會收到一條錯誤消息，指出LastName缺失，這很好。但是，當你填寫姓氏時，錯誤信息會保留（當你移動到不同的輸入字段時）。看到這個截圖： enter image description here
