所以我有一个组合框，它是为某个视图动态加载的。每当我将queryMode设置为remote时，如果我单击组合框，它就会加载数据，但如果设置为local，它就不会显示任何数据。我的商店将正确返回请求的数据，只是它不会显示在组合框中。
我是不是遗漏了什么？希望有人能帮助我。
这是我的带有组合框的视图控制器：

Ext.define('Stm.controller.HpUpdate', {
    extend: 'Ext.app.Controller',

    requires: [
        'Stm.view.contents.hpupd.Detail'
    ],

    stores: [
        'SiteDomain'
    ],

    fromDetail: false,
    isAbort: false,
    isDataSeted: false,
    firstSorters: undefined,
    recordId: undefined,
    isUpdate: false,

    init: function() {
        this.callParent(arguments);
        console.log(Ext.getDisplayName(arguments.callee));

        this.control({
            'hup-list': {
                afterRender: this.setupStmList
            }
        });

        this.addRef([{
                ref: 'list',
                selector: 'hup-list'
            },
            {
                ref: 'detail',
                selector: 'hup-detail'
            },
        ]);
    },

    setupStmList: function() {
        console.log(Ext.getDisplayName(arguments.callee));

        var me = this;
        var store = me.getSiteDomainStore();
        var record = Cps.Util.baseRecord();

        store.load({
            params: param,
            callback: function(records, operation, success) {
                var response = operation.response;
                if (!response || response.length === 0) {
                    return;
                }

                var responseText = response.responseText;
                if (!responseText || responseText.length === 0) {
                    return;
                }
                var res = Ext.decode(responseText);

                if (res.common.st === 'mainte' || res.common.st === 'abort') {
                    return;
                }

                if (res.common.st === 'ng') {
                    Cps.Util.alert(res.common.msg);
                    return;
                }
                if (records.length === 0) {
                    return;
                }

                me.getList().down('#dtAplDateTimeFrom').down('#dateField').focus();
            }
        });

        me.firstSorters = this.getHpUpdateStore().getSorters();
    },
});

这是我的观点：

Ext.define('Stm.view.contents.hpupd.List', {
     extend: 'Ext.container.Container',
     alias: 'widget.hup-list',
     layout: {
         type: 'vbox',
         align: 'stretch'
     },

     items: [{
         xtype: 'cps-combobox',
         fieldLabel: 'Domain',
         itemId: 'cmbSiteDomain',
         queryMode: 'local',
         store: {
             type: 'sitedomain'
         },
         width: 350,
         displayField: 'siteDomain',
         valueField: 'siteId',
     }],
 });

商店：

Ext.define('Stm.store.SiteDomain', {
extend: 'Extends.data.Store',
alias: 'store.sitedomain',
requires: [
    'Cps.Setting',
    'Stm.model.SiteInfo'
],

model: 'Stm.model.SiteInfo',

pageSize: Stm.Const.controller.dataCountLimit,
proxy: {
    type: 'ajax',
    url: Cps.Setting.getEntryUrl() + '/stm/st-update/site-domain',
    reader: {
        type: 'json',
        rootProperty: 'data'
    },
    actionMethods: {
        create: 'POST',
        read: 'POST',
        update: 'POST',
        destroy: 'POST'
    }
}
});
