MVC发布列表的奇怪行为

我在视图中有以下动态创建的文本框:

 @for (int i = 0; i < Model.MullionList.Count; i++)
{
    ItemDrops curMullItem = Model.MullionList.ElementAt(i);
    <div class="form-group">
        @Html.Label(curMullItem.ItemName.ToString(), new { @class = "col-sm-6 control-label" })

        <div class="col-sm-6">
            @Html.TextBoxFor(x => x.MullionList[i].ItemPossInfo, new { @class = "form-control" })
            @Html.HiddenFor(x => x.MullionList[i].ItemName)
        </div>
    </div>                                
}

我偶然注意到某些类型的产品在发布时(对于MullionList)返回null,即使我选择了这些下拉列表。

因此它适用于某些产品,但不适用于其他产品。

甚至更奇怪的部分是当我在视图中进一步向下移除此部分时(即表格发布时MulionList不为空)

 <div class="form-group">
    @Html.Label("Glass", new { @class = "col-sm-6 control-label", id = "glass-first-label" })
    <div class="col-sm-6">
        @Html.DropDownListFor(gu => gu.GlassItems[0].Value, Model.GlassTypes, "-- Select --", new { @class = "form-control glass-multi-select", id = "Glass" + 0 })
    </div>
</div>

<div id="hidden-glass-select" style="display: none">
    @for (int i = 1; i < Model.GlassUnitsCount; i++)
    {
        var glassUnit = Model.GlassUnits.ElementAt(i);
        <div class="form-group">
            @Html.Label(glassUnit.ToString(), new { @class = "col-sm-6 control-label" })
            <div class="col-sm-6">
                @Html.DropDownListFor(gu => gu.GlassItems[i].Value, Model.GlassTypes, "-- Select --", new { @class = "form-control glass-multi-select", id = "Glass" + i })
            </div>
        </div>

    }
</div>

<div class="form-group">
    @Html.LabelFor(go => go.GlazzingInfoVal, "Glazzing Option", new { @class = "col-sm-6 control-label" })
    <div class="col-sm-6">
        @Html.DropDownListFor(go => go.GlazzingInfoVal, Model.GlazzingOptions, "-- Select --", new { @class = "form-control" })
    </div>
</div>

我想我现在已经解决了这个问题。

我重命名了所有项目(以Glass或Glazzing开头的列表,它可以工作!)

这看起来像是一个合适的MVC错误
