Question

我是SAPUI5的新手。我正在尝试从清单文件中加载JSON模型，并通过“路由和导航”将JSON对象作为参数发送。

我只有一个视图，因此我试图以一种简单的形式绑定数据。我遇到一个错误：

View1.controller.js？eval：8未捕获（承诺）TypeError：无法读取未定义的属性“ getModel”

请帮助我解决错误。

Answer 1

View1未被组件初始化，因此无法确定所有者。无需显式创建视图并将其放入DOM（index.html）中，而是像在带注释的代码中那样创建sap.m.Shell。 Shell将创建一个组件，该组件将创建manifest.json中指定的根视图。
