MVC3 远程验证未触发？

我创建了一个非常简单的测试项目来说明这个问题。

我的模型类

public class HomeModel
{
    [Required(ErrorMessage="Missing property1.")]
    public string Property1
    {
        get;
        set;
    }

    [Remote("ValidateProperty2", "Home", HttpMethod="Get",  AdditionalFields = "Property3", ErrorMessage="Property2 wrong!")]
    public string Property2
    {
        get;
        set;
    }

    public string Property3
    {
        get;
        set;
    }
}

我的控制器

public class HomeController : Controller
{
    public ActionResult Index()
    {
        HomeModel model = new HomeModel();
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(HomeModel model)
    {
        return View(model);
    }

    public ActionResult ValidateProperty2(string property2, string property3)
    {
        return Json(true, JsonRequestBehavior.AllowGet);
    }
}

和我的视图

@model RemoteValidationTest.Models.HomeModel

@{
Layout = null;
}

<!DOCTYPE html>

<html>
<head>
<title>Index</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
</head>
<body>
@using (Ajax.BeginForm(new AjaxOptions
{
    HttpMethod = "POST"
}))
{
    @Html.TextBoxFor(x => x.Property1) @Html.ValidationMessageFor(x => x.Property1)<br />
    @Html.TextBoxFor(x => x.Property2) @Html.ValidationMessageFor(x => x.Property2)<br />
    @Html.TextBoxFor(x => x.Property3) @Html.ValidationMessageFor(x => x.Property3)<br />

    <input type="submit" />
}
</body>
</html>

和我的 web.config

<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>

这里没有什么特别的。我有一个具有 3 个属性的模型类。第一个是必需的，第二个是远程验证，我相信我已经正确创建了操作方法。我将中断点设置为 ValidateProperty2 函数，它永远不会被调用。

我还使用了FireBug，同样的事情客户端甚至不会尝试调用服务器端。

这里的代码有什么问题吗？

编辑1：我想我得到了一些东西，只有当控件（例如文本框）在侧面具有值时才会触发远程验证。空控件永远不会触发验证。就我而言，我实际上尝试实现更复杂的逻辑，即使控制文本为空（以检查其他属性的值），我也需要触发验证。有可能吗？

原文

I created a very simple test project to illustrate the problem.

My model class

public class HomeModel
{
    [Required(ErrorMessage="Missing property1.")]
    public string Property1
    {
        get;
        set;
    }

    [Remote("ValidateProperty2", "Home", HttpMethod="Get",  AdditionalFields = "Property3", ErrorMessage="Property2 wrong!")]
    public string Property2
    {
        get;
        set;
    }

    public string Property3
    {
        get;
        set;
    }
}

My controller

public class HomeController : Controller
{
    public ActionResult Index()
    {
        HomeModel model = new HomeModel();
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(HomeModel model)
    {
        return View(model);
    }

    public ActionResult ValidateProperty2(string property2, string property3)
    {
        return Json(true, JsonRequestBehavior.AllowGet);
    }
}

And my view

@model RemoteValidationTest.Models.HomeModel

@{
Layout = null;
}

<!DOCTYPE html>

<html>
<head>
<title>Index</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
</head>
<body>
@using (Ajax.BeginForm(new AjaxOptions
{
    HttpMethod = "POST"
}))
{
    @Html.TextBoxFor(x => x.Property1) @Html.ValidationMessageFor(x => x.Property1)<br />
    @Html.TextBoxFor(x => x.Property2) @Html.ValidationMessageFor(x => x.Property2)<br />
    @Html.TextBoxFor(x => x.Property3) @Html.ValidationMessageFor(x => x.Property3)<br />

    <input type="submit" />
}
</body>
</html>

And my web.config

<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>

Nothing really fancy here. I havea model class with 3 properties. The first one is set be required and second one is remote validation, I believed I have create the action method properly. I set break piont to ValidateProperty2 function, it never gets called.

I also used FireBug, the same thing client side does not even try to call the server side.

What is wrong with the code here?

Edit 1:
I think I get something, the remote validation will only fires when the control (e.g text box) has value in side. The empty control will never trigger the validation. In my case I actually try to implmenet a more complicated logic, I need the validation to fire even when the control text is empty (to check other property's value). Is it even possible?
