Question

我的模型中有一个IEnumerable<string>值的属性，它从复选框数组中获取值。如果没有选中复选框，Fubu会以绑定错误响应。

Fubu会寻找各种潜在的价值来源。当它最终检查Cookies时，它会引发异常：

System.NotSupportedException
   в FubuMVC.Core.Http.Cookies.CookieValueSource.GetChildren(String key) в c:\BuildAgent\work\ae412c8ad89b884b\src\FubuMVC.Core\Http\Cookies\CookieValueSource.cs:строка 46

绑定代码将此异常解释为绑定失败，并返回以下continuation（“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外，我该如何正确地做到这一点？我正在使用最新的公共NuGets：FubuCore 1.1.0和FubuMVC.Core 1.1.0。

绑定到FubuMVC中的空IEnumerable会导致绑定错误
