前几天我发了一个问题，没有得到太多回应。我尝试了几件事，但仍然没有运气。我正在尝试在 GWTP 中嵌套一个选项卡演示器。我有一帧（北）是选项卡组 1 和一帧（西）是选项卡组 2。当我与组 1 交互时，我更新了控制组 2 的嵌套选项卡演示器。我查看了嵌套选项卡的示例演示者，但我无法从中确定我的错误。
两个 TabContainerPresenter 是 ManagementTabsPresenter 和 SettingsTabsPresenter。这些的孩子就像下面的 HomePresenter。这些子项的内容显示在位于 MainPreseter 的 DockLayoutPanel 的中心。我希望 ManagementTabsPresenter 和 SettingsTabsPresenter 显示在同一个 DockLayoutPanel 的 West 插槽中。
当我运行此代码时，所有内容都放置在屏幕上的正确位置。您甚至可以单击选项卡并执行操作。问题始于首先显示 SettingsPresenter，即使默认页面是 HomePresenter。就像它试图在启动时同时显示两者一样。然后，当您选择属于 ManagementTabsPresenter 或 SettingsTabsPresenter 的任何选项卡时，它将在 MainPresenter.Center_Slot 中打开正确的内容，但在 MainPresenter.West_Slot 中显示不正确的演示者。我无法弄清楚这里出了什么问题。任何帮助，将不胜感激。
