我想在SAPUI5应用程序中使用绝对路径，以便直接访问单个资源。
根据http://help.sap.com/saphelp_nw75/helpdata/de/6c/47b2b39db9404582994070ec3d57a2/content.htm它应该有用。
但是当我使用类似的东西时：
<Text text="{users>/Users('123')/LastName}" />
无法获取数据。
有谁知道这里有什么问题？
答案 0 :(得分：2)
使用属性的参数化路径时，似乎不会自动加载该值。
要访问参数定义的对象，可以在控件上为该对象指定element binding，然后以相对方式引用该属性：
