MasterDetail页面上的错误

Question

所以我试图在SAP Web IDE上重新创建 app ：

但我不断收到错误：

这是我的App.Controller.js代码：

sap.ui.define([
    "pt/procensus/ui5rv/controller/BaseController",
    "sap/ui/model/json/JSONModel"
], function (BaseController, JSONModel) {
    "use strict";

    return BaseController.extend("pt.procensus.ui5rv.controller.App", {

        onInit : function () {
            var oViewModel,
                fnSetAppNotBusy,
                oListSelector = this.getOwnerComponent().oListSelector,
                iOriginalBusyDelay = this.getView().getBusyIndicatorDelay();

            oViewModel = new JSONModel({
                busy : true,
                delay : 0
            });
            this.setModel(oViewModel, "appView");

            fnSetAppNotBusy = function() {
                oViewModel.setProperty("/busy", false);
                oViewModel.setProperty("/delay", iOriginalBusyDelay);
            };


            this.getOwnerComponent().oWhenMetadataIsLoaded.
                then(fnSetAppNotBusy, fnSetAppNotBusy);

            // Makes sure that master view is hidden in split app
            // after a new list entry has been selected.
            oListSelector.attachListSelectionChange(function () {
                this.byId("idAppControl").hideMaster();
            }, this);

            // apply content density mode to root view
            this.getView().addStyleClass(this.getOwnerComponent().getContentDensityClass());
        }

    });

}
);

这是我的Base.Controller.js代码：

    /*global history */
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/ui/core/routing/History"
], function(Controller, History) {
"use strict";

return Controller.extend("pt.procensus.ui5rv.controller.BaseController", {
    /**
     * Convenience method for accessing the router in every controller of the application.
     * @public
     * @returns {sap.ui.core.routing.Router} the router for this component
     */
    getRouter: function() {
        return this.getOwnerComponent().getRouter();
    },

    /**
     * Convenience method for getting the view model by name in every controller of the application.
     * @public
     * @param {string} sName the model name
     * @returns {sap.ui.model.Model} the model instance
     */
    getModel: function(sName) {
        return this.getView().getModel(sName);
    },

    /**
     * Convenience method for setting the view model in every controller of the application.
     * @public
     * @param {sap.ui.model.Model} oModel the model instance
     * @param {string} sName the model name
     * @returns {sap.ui.mvc.View} the view instance
     */
    setModel: function(oModel, sName) {
        return this.getView().setModel(oModel, sName);
    },

    /**
     * Convenience method for getting the resource bundle.
     * @public
     * @returns {sap.ui.model.resource.ResourceModel} the resourceModel of the component
     */
    getResourceBundle: function() {
        return this.getOwnerComponent().getModel("i18n").getResourceBundle();
    },

    /**
     * Event handler  for navigating back.
     * It checks if there is a history entry. If yes, history.go(-1) will happen.
     * If not, it will replace the current entry of the browser history with the master route.
     * @public
     */
    onNavBack: function() {
        var sPreviousHash = History.getInstance().getPreviousHash();

        if (sPreviousHash !== undefined) {
            // The history contains a previous entry
            history.go(-1);
        } else {
            // Otherwise we go backwards with a forward history
            var bReplace = true;
            this.getRouter().navTo("master", {}, bReplace);
        }
    }

});

});

我的应用文件夹：

我无法理解为什么会这样。我已经删除了'then'部分，它给了我更多错误......：/

非常感谢任何帮助：）

你能试试吗？至少这是它在我的App.controller中的工作方式：

 this.getOwnerComponent().getModel().metadataLoaded()
            .then(fnSetAppNotBusy, fnSetAppNotBusy);
