，你可以看到我inlude零售客户视图在零售状态儿童一个viewstack以及批发状态下的批发客户观点。问题是，当我运行我的应用程序时，它们不会出现在两种状态中。

任何想法？

Answer 1

这对我来说很奇怪。 ViewStack的全部目的是一次只显示一个项目。这是一个非常奇怪的方法。

我看到你有一个tabbar，其dataProvider是ViewStack。但是，您的ViewStack不是作为组件的可绑定属性创建的，而且您似乎从未设置过初始状态。因此，我推断，这种情况正在发生：

1. 在默认状态下，这是空字符串
2. ViewSTack和/或的TabBar没有这些孩子被初始化出于某种原因
3. 应用程序状态的变化应用程序加载
4. TabBar不更新

CreationPolicy也可能会发挥作用，但我不确定。你必须通过代码来弄清楚发生了什么。我强烈建议你考虑一个替代方法。可能基于用户安全设置或当前状态手动创建tabbar导航器dataProvider。
