javascript - SAPUI5 使用来自 XMII 的 OData 填充 SmartTable

Question

我目前正在尝试使用我们的 MII 服务器中的 OData 填充智能表(xml View )。我不断收到以下错误:

错误:无法从 ./Component-changes.json 加载资源 PATH/Component-changes.json。检查“未找到文件”或解析错误。原因:未找到 -“getChanges”失败:-

这是我的 Main.controller.js:

sap.ui.controller("PATH.view.Main", {

/**
* Called when a controller is instantiated and its View controls (if available) are already created.
* Can be used to modify the View before it is displayed, to bind event handlers and do other one-time initialization.
* @memberOf sapui5.Main
*/
onInit: function() {
    var oModel, oView;
    this.oUpdateFinishedDeferred = jQuery.Deferred();
    this.getView().byId("main").attachEventOnce("updateFinished", function(){
        this.oUpdateFinishedDeferred.resolve();
    }, this);
         sap.ui.core.UIComponent.getRouterFor(this).attachRouteMatched(this.onRouteMatched , this);

    var oModel, oView;
    oModel = new sap.ui.model.odata.ODataModel("http://server:port/XMII/IlluminatorOData/QueryTemplate?QueryTemplate=MessageMonitor%2FTemplates%2FQuery%2FMIILogDetailsQry&Content-Type=text%2Fxml", {annotationURI: "/XMII/IlluminatorOData/$metadata"});

    jQuery.sap.log.error(oModel.getMetaModel());
    oModel.setCountSupported(false);
    var oTable = this.getView().byId("oTable");
    oTable.setEntitySet("Messages");
    oTable.setModel(oModel);
    oView = this.getView();
    oView.setModel(oModel);
    oTable.rebindTable();
},
onRouteMatched : function(oEvent) {
     var oList = this.getView().byId("main");
     var sName = oEvent.getParameter("name");
     var oArguments = oEvent.getParameter("arguments");
    // Wait for the list to be loaded once
     jQuery.when(this.oUpdateFinishedDeferred).then(jQuery.proxy(function() {
     var aItems;
         // On the empty hash select the first item
         if (sName === "main") {
             //this.selectDetail();
         }
         // Try to select the item in the list
         if (sName === "product") {
             aItems = oList.getItems();
             for (var i = 0; i < aItems.length; i++) {
                 if (aItems[i].getBindingContext().getPath() === "/" +
                         oArguments.product) {
                     oList.setSelectedItem(aItems[i], true);
                     break;
                 }
             }
         }
     }, this));
},
});

我正在服务器本身上进行开发，因此我对否则会遇到的 CORS 错误没有任何问题。

我的Main.view.xml:

<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m" xmlns:smartFilterBar="sap.ui.comp.smartfilterbar" xmlns:smartTable="sap.ui.comp.smarttable" controllerName="PATH.view.Main" height="100%" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:app="http://schemas.sap.com/sapui5/extension/sap.ui.core.CustomData/1">
<Page id="main" title="{i18n>PageTitle}" showNavButton="false">
<Toolbar></Toolbar>
    <content>
    <smartFilterBar:SmartFilterBar id="smartFilterBar" entityType="Messages" persistencyKey="SmartFilter_Explored">
    <smartFilterBar:controlConfiguration>            
      <smartFilterBar:ControlConfiguration key="CATEGORY">
      <smartFilterBar:defaultFilterValues>
          <smartFilterBar:SelectOption low="i">
          </smartFilterBar:SelectOption>

      </smartFilterBar:ControlConfiguration>          
      <smartFilterBar:ControlConfiguration key="DATETIME">

            </smartFilterBar:SelectOption>
          </smartFilterBar:defaultFilterValues>
        </smartFilterBar:ControlConfiguration>
      </smartFilterBar:controlConfiguration>          
    </smartFilterBar:SmartFilterBar>

        <smartTable:SmartTable id="oTable" entitySet="Messages" 
        smartFilterId="smartFilterBar" tableType="Table" 
        useExportToExcel="false" useVariantManagement="false" 
        useTablePersonalisation="false" header="Messages" 
        showRowCount="false" 
        persistencyKey="SmartTableAnalytical_Explored" 
        enableAutoBinding="true" />
    </content>

我的 Component.js、index.html 和 MyRouter.js 是根据 SAP Hana 分步指南为您的第一个应用程序设置的。

我完全不知道问题是什么。

提前致谢。

Answer 1

读取文件 component-changes.json 以进行变体管理，但这不应阻止加载智能表中的数据。既然您设置了enableAutoBinding，系统是否会调用您的服务/消息？
