mvc 4中的服务器端验证不显示错误

Question

任何人都可以告诉我为什么当我关闭javascript时，下面的代码没有返回错误消息，我正在检查以确保服务器端验证有效。

我可以在Modelstate.isvalid上设置断点并查看错误消息。

@model Web.Domain.WeightsAndMeasures.DisplayWeightsAndMeasures

<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

@using (Html.BeginForm("CalculateWeightOrMeasure", "WeightsMeasures", FormMethod.Post, new { @id = "frmWeightsMeasures" }))
{
@Html.ValidationSummary(true)

<fieldset>
    <legend>DisplayWeightsAndMeasures</legend>

    <div class="editor-label">
        @Html.LabelFor(model => model.dblValueToConvert)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.dblValueToConvert)
        @Html.ValidationMessageFor(model => model.dblValueToConvert)
    </div>

    <p>
        <input type="submit" value="Save" />
    </p>
</fieldset>
}

[HttpPost]
    public ActionResult CalculateWeightOrMeasure(FormCollection fc, DisplayWeightsAndMeasures model)
        {
         if (ModelState.IsValid)
            {
            var data = _IGWAM.GetWeightsMeasures();
            string ConvertFrom = fc["dblValueToConvert"];
            return PartialView("WeightOrMeasureForm", model);
                 }
         return View("~/Views/Home/Index.cshtml", model); <--This does not work
         //return PartialView("WeightOrMeasureForm", model); <--This does work, 
        }

我正在使用MVC4
