odata - 无法读取未定义的属性“getODataEntitySet”

Question

我正在尝试使用SmartFilterBar，如下所示：

风景：

<smartFilterBar:SmartFilterBar id="smartFilterBar" considerSelectionVariants="true" entitySet="ZMD_C_CLASS_OBJECT">
    <smartFilterBar:controlConfiguration>
        <smartFilterBar:ControlConfiguration key="ClassType" visibleInAdvancedArea="true" preventInitialDataFetchInValueHelpDialog="false"></smartFilterBar:ControlConfiguration>
    </smartFilterBar:controlConfiguration>
</smartFilterBar:SmartFilterBar> 

视图的控制器：

onInit: function () {
    const oModel = this.getModel("ClassSelect");
    this.getView().setModel(oModel);
},

在dataSources清单中定义为：

"dataSources": {
    "ZMD_C_CLASS_OBJECT_CDS": {
        "uri": "/sap/opu/odata/sap/ZMD_C_CLASS_OBJECT_CDS/",
        "type": "OData",
        "settings": {
            "odataVersion": "2.0",
            "localUri": "localService/metadata.xml"
        }
    }
}

和模型

"ClassSelect": {
    "uri": "/sap/opu/odata/sap/ZMD_C_CLASS_OBJECT_CDS/",
    "type": "sap.ui.model.odata.v2.ODataModel",
    "settings": {
        "defaultOperationMode": "Server",
        "defaultBindingMode": "OneWay",
        "defaultCountMode": "Request"
    },
    "dataSource": "ZMD_C_CLASS_OBJECT_CDS",
    "preload": true
}

编译器抱怨：

我究竟做错了什么？
