UI5 sometimes throws error: Control with ID ... could not be found - EventProvider sap.m.routing.Target

Question

随机地，登录 (SAP NetWeaver) 到 SAPUI5 页面后，SAPUI5 抛出错误 ID 为 rootControl 的控件 - EventProvider sap.m.routing.Target。我试图强制错误登录和注销。经过多次尝试（40 次，有时 102 次...），出现错误。

我的根控件是 App.view.xml 中的 <App id="rootControl">。

有什么想法吗？

Randomly SAPUI5 throws error ...

我记得在过去的 UI5 版本中由于 竞争条件 而遇到同样的问题：

启动应用程序时，Component.js 由于 sap.ui5/rootView/async: true 而异步检索根视图。
Component.js中的init通常会初始化路由器，该路由器检索与哈希值对应的目标视图，而根视图仍在加载。
有时，根视图无法在目标视图之前完全加载，这会导致错误 → 目标不知道将其视图放在哪里。

commit:d054bc1 确保目标等待根视图完全加载。该修复程序随 1.54 一起发布，但根据更改日志，应该也可以在 1.52.5+ 中使用。要查看应用程序是哪个 UI5 版本运行，请按 Ctrl + Left Alt + Shift + P。请升级UI5 lib到最新稳定版

我不建议同步加载根视图。
