sapui5 - UI5 有时会抛出错误 : Control with ID . .. 无法找到 - EventProvider sap.m.routing.Target

Question

登录 (SAP NetWeaver) 到 SAPUI5 页面后，SAPUI5 随机抛出错误无法找到 ID rootControl 的控件 - EventProvider sap.m.routing.Target。我尝试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。

我的根控制是<App id="rootControl">在App.view.xml 。

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了同样的问题:

1. 启动应用程序时，Component.js由于 sap.ui5/rootView/async: true 异步检索 Root View .
2. init Component.js内通常会初始化路由器，当 Root View 仍在加载时检索与哈希值对应的目标 View 。
3. 有时， Root View 无法在目标 View 之前完全加载，从而导致错误 → 目标不知道将其 View 放在哪里。

commit:d054bc1 确保目标等到 Root View 完全加载。 该修复已在 1.54 中发布，但根据更改日志，也应该在 1.52.5+ 中可用。 要查看应用程序正在运行的 UI5 版本，请按 Ctrl + Left Alt + Shift + P 。请将UI5 lib升级到最新稳定版本。

我不建议同步加载 Root View 。
