asp.net-mvc-3 – 不为CompareAttribute DataAnnotation触发客户

[Required]
    [RegularExpression(@"(S)+",ErrorMessage = "White space is not allowed")]
    [StringLength(20,MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "New Password")]
    public string NewPassword { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [RegularExpression(@"(S)+",MinimumLength = 6)]
    [Display(Name = "Confirm Password")]
    [Compare("NewPassword",ErrorMessage = "The new password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

这是我的观看代码：

<table class="fieldset center" width="400">
    <tbody>
        <tr>
            <th width="150">
                @Html.LabelFor(m => m.NewPassword)
            </th>
            <td>
                @Html.PasswordFor(m => m.NewPassword,new { @class = "itext3" })
                <br /><br />@Html.ValidationMessageFor(m => m.NewPassword)
            </td>
        </tr>                       
        <tr>
            <th width="150">
                @Html.LabelFor(m => m.ConfirmPassword)
            </th>
            <td>
                @Html.PasswordFor(m => m.ConfirmPassword,new { @class = "itext3" })
                <br /><br />@Html.ValidationMessageFor(m => m.ConfirmPassword)
            </td>
        </tr>
    </tbody>
</table>

测试时,所有属性都会触发客户端验证消息,但ConfirmPassword上的CompareAttribute除外,直到我点击服务器才触发.但是,在我的控制器中,ModelState.IsValid = false.

我将我正在做的事情与正常工作的默认MVC应用程序进行了比较.有关故障排除和修复的建议吗？

我正在使用MVC 3 RTM.
