在 FubuMVC 中绑定到空的 IEnumerable 会导致绑定错误

Question

我的模型中有一个IEnumerable<string>值属性，它从复选框数组中获取值。如果未选中任何复选框，Fubu 将响应绑定错误。

发生的事情是，Fubu寻找各种潜在的价值来源。当它最终检查 Cookie 时，它会抛出异常：

System.NotSupportedException
   в FubuMVC.Core.Http.Cookies.CookieValueSource.GetChildren(String key) в c:BuildAgentworkae412c8ad89b884bsrcFubuMVC.CoreHttpCookiesCookieValueSource.cs:строка 46

绑定

代码将此异常解释为绑定失败，并返回以下延续（"Packages"是属性的名称）：

{"success":false,"refresh":false,"errors":[{"category":null,"field":"Packages","label":"en-US_Packages","message":"Data is formatted incorrectly"}]}

除了添加假隐藏字段之外，我如何正确执行此操作？我使用的是最新的公共NuGets：FubuCore 1.1.0和FubuMVC.Core 1.1.0。
