sapui5 - 如何正确分配bindProperty中的路径？

Question

我创建了一个 sap.m.ObjectIdentifier 对象，并将属性绑定(bind)到路径，如下所示:

const oObjectIdentifier = new ObjectIdentifier();
oObjectIdentifier.bindProperty("title", {
    path: "{Objects>Object}"
});
oObjectIdentifier.bindProperty("text", {
    path: "{Objects>Objecttext}"
});

它是 Tree 的聚合表:

this.byId("ClassObjectTable").bindItems({
    path: "Objects>/",
    template: oColList
});

之前，我做了以下操作:

const oObjectIdentifier = new ObjectIdentifier({
    title: "{Objects>Object}",
    text: "{Objects>Objecttext}"
});

并且成功了。
我做错了什么？

Answer 1

oObjectIdentifier.bindProperty("title", {
  path: "{Objects>Object}"
});

What am I doing wrong?

path 值的语法无效。删除大括号:

oObjectIdentifier.bindProperty("title", {
  path: "Objects>Object"
});
