我正在尝试使用我的三个级别的OData服务在我的应用程序中构建一些sap.uxap.ObjectPageLayout。当我尝试将"块"聚合绑定为"{路径：'节点'，模板：oTemplate}"时，它不会完成模板中的绑定，并且控制台会记录许多错误。

我解决了每次生成模板控件时执行元素绑定的方法。但它为每个条目调用服务一次，而不是创建绑定并调用批处理请求中的所有属性。

有什么想法可以改善这一点吗？
谢谢和问候，拉斐尔·洛佩兹
很好，我在解决方法的代码中发现了一个错误。我没有正确扩展第一个元素绑定，它应该是：$expand=订单/客户我想这是我测试中的一个错字。
无论如何，第一个代码段不起作用，似乎 Blocks 聚合包含指向 url 的另一个"$expand"参数，并且错误出现在控制台中
