SAPUI5 路由抛出错误“找不到控件（应用程序控件的 ID）”

Question

这个问题来自这个答案（我无法运行源代码），我的要求与这个问题类似，这是一个带有应用程序控件的页面，导航到一个带有一个主视图和一个详细信息视图的 SplitContainer。Master.view.xml 加载成功，但我得到

“无法找到带有 ID 应用程序的控件”

单击项目时出错。

      "viewId": "detailNoObjectsAvailable"
    }
  }
}

我不确定子路由是否仍然需要这么多目标。而且我知道问题出 "targetControl" : "app"在"split"路由上，但是如果我在路由中添加“targetControl”：“idAppControl” "object"，它也会产生

无法找到 ID 为 idAppControl 的控件

而 这个回答 说：

您不能加入与父路由相同的控件。

我现在真的很困惑。

我也试过 delete "rootview"in "sap.ui5"，不起作用。

欢迎任何帮助！提前致谢！

Answer 1

感谢这个路由配置文档，我解决了我的问题。

我以为是"targetControl": "app"在split路由中导致了这个错误，但实际上是因为"controlId": "app"在路由routing.config中导致了这个问题。

config 参数定义路由配置的默认值。

更改后，我遇到了另一个错误：

目标工作列表没有设置 controlId，也没有父项，因此无法显示目标。

所以我target在worklist路由中删除并添加targetControl: app了它，因为它不再有默认targetControl值。

这是新的路由配置：
