SAP UI5 绑定问题。从 Odata 获取的数据，但由于嵌套数组中的绑定问题而未显示在视图中

Question

我创建了一个 fiori 应用程序并尝试使用控制器中的 odata 读取功能获取数据。在视图中访问数据的正确方法是什么。 工作正常的后端请求：/sap/opu/odata/sap/ZodatSRV/empSalesSet?$expand=set1,set2,set3,set4,set5&$filter=(category eq 'empSales')

查看不起作用的代码：

<Text text="{/category}"></Text>
    <Text text="{empSalesSet/category}"></Text>
<Text text="{category}"></Text>

从结果集中访问数据的正确方法是什么？我需要对视图进行任何特定的绑定吗？请让我知道我错过了什么。

控制器代码：

onInit: function () {

            var oDataModel = this.getView().getModel();
            var aFilter = [];
            var oFilter = {};

            oFilter = new Filter("category", FilterOperator.EQ, "empSales");
            aFilter = [oFilter];

            oDataModel.read("/empSalesSet", {
                urlParameters: {
                    "$expand": "set1,set2,set3,set4,set5"
                },
                filters: aFilter,
                success: function (data, response) {},
                error: function (oError) {}
            });

        }

在 Chrome 控制台中，我可以看到数据以 json 格式作为嵌套数组出现

在 xml 视图中应该使用什么语法来显示来自集合 3 数组的数据，集合 4
