我有一个适用于SAP Web IDE（个人版）的应用程序。我在我的后端系统中部署了应用程序，当我开始测试并且出乎我意料之外，在我尝试保存错误条目之后（想看看错误消息是否按预期发送），我收到了错误 ＆＃34;无法阅读财产＆＃39; getParent＆＃39;未定义＆＃34; 。 ＆＃34;未定义＆＃34;指的是我在基本控制器中使用的消息弹出窗口。异常不在我的代码中发生，但在 MessagePopover-dbg.js 中（下面附有快照，错误1209中的行）。
Web IDE上的SAPUI5版本：1.44.12
后端系统上的SAPUI5版本：1.44.23
基本控制器代码，以及调用下面附带的弹出窗口的例程。在其他情况下，我通常会向SAP发出一份说明，但由于我是SAPUI5的新成员，我并非100％确定我没有遗漏任何内容。有什么想法吗？

这不是像'I.B.N那样的流行音乐。在评论部分注意到，问题是负责屏幕上弹出位置的控件的声明。它是使用sap.ui.getCore（）和控件的完全限定路径声明的，这是非常不明智的，因为它在运行时和不同环境中动态生成可能会发生变化......
