extjs – 无法解析“c不是构造函数”错误

我想要的只是两个网格从远程JSON文件中获取数据,但无论我做什么,我都会继续获取主题中的错误.

这是我的简单代码：

app.js：

Ext.Loader.setConfig({enabled:true});

Ext.application({
    name: 'GeoSniffer',autoCreateViewport: true,models: ['Location','Client'],stores: ['Locations','Clients'],});

Viewport.js

Ext.define('GeoSniffer.view.Viewport',{
    extend: 'Ext.container.Viewport',layout: 'fit',requires: [
        'GeoSniffer.view.ClientsList','GeoSniffer.view.LocationsList'
    ],initComponent: function() {
        this.items = {
            layout: {
                type: 'hbox',align: 'stretch'
            },items: [{
                width: 250,xtype: 'panel',id: 'west-region',layout: {
                    type: 'vbox',align: 'stretch'
                },items: [{
                    xtype: 'locationslist',flex: 1
                },{
                    xtype: 'clientslist',flex: 1             
                }]
            }]
        };

        this.callParent();
    }
});

Client.js：

Ext.define('GeoSniffer.model.client',{
    extend: 'Ext.data.Model',fields: [
        'ip','packetsCount','firstPacketUsec','latestPacketUsec','location','sessionsArr','currentSession'
    ]
});

Location.js：

Ext.define('GeoSniffer.model.Location',fields: [
        'countryCode','countryName','region','city','postalCode','latitude','longitude','dma_code','area_code','metro_code','currentSession','clients'
    ]
});

Clients.js：

Ext.define('GeoSniffer.store.Clients',{
    extend: 'Ext.data.Store',requires: 'GeoSniffer.model.Client',model: 'GeoSniffer.model.Client',autoLoad: false,proxy: {
        type: 'ajax',url: 'data/clients.json',reader: {
            type: 'json',root: 'clients_list'
        }
    }
});

Locations.js：

Ext.define('GeoSniffer.store.Locations',requires: 'GeoSniffer.model.Location',model: 'GeoSniffer.model.Location',url: 'data/locations.json',root: 'locations_list'
        }
    }
});

ClientsList.js：

Ext.define('GeoSbiffer.view.ClientsList',{
    extend: 'Ext.grid.Panel',alias: 'widget.clientslist',store: 'Clients',title: 'Clients',hideHeaders: true,initComponent: function() {
        this.columns = [
            {
                dataIndex: 'ip',},{
                dataIndex: 'packetsCount',}

        ];

        this.callParent();
    }
});

LocationsList.js：

Ext.define('GeoSbiffer.view.LocationsList',alias: 'widget.locationslist',store: 'Locations',title: 'Locations',initComponent: function() {
        this.columns = [{
            dataIndex: 'countryName',flex: 1
            },{
            dataIndex: 'city',flex: 1             
            }

        ];

        this.callParent();
    }
});

clients.json

{
    "sessions_arr": [ 7,6,1,8,2,39,5,12,8],"clients_list": [
      {
        "ip": "82.166.201.153","packetsCount": 1,"firstPacketUsec": 211474,"latestPacketUsec": 211474,"location": {

        },"sessionsArr": [1,0],"currentSession": 1
      }
    ],"status": {
      "executionResult": "OK","isSnifferActive": false,"servletInfo": ""
    }
}

locations.json

{
    "sessions_arr": [ 7,"locations_list": [
      {
        "countryCode": "US","countryName": "United States","region": "CA","city": "Palo Alto","postalCode": "94304","latitude": 37.376205,"longitude": -122.1826,"dma_code": 807,"area_code": 650,"metro_code": 807,"packetsCount": 2,"sessionsArr": [ 2,"clients": [
          {
            "ip": "69.171.242.14","firstPacketUsec": 368942,"latestPacketUsec": 369060,"currentSession": 0
          }
        ]
      }
    ],"servletInfo": ""
    }
}

试图通过堆栈跟踪调试Firebug没有提供任何有用的信息.

我错过了什么？
