我正在尝试从 4.0.7 升级到 Extjs4.1 我的应用程序窗口现在似乎很好，但所有网格和树中都没有显示数据！尽管数据是从服务器端返回的，即使我用于菜单的静态文件（如布局浏览器示例中）也不起作用

这是我的 menu.json

{ 
text: '.',
children: [{

                    text:'Dashboard - <font size=1>Overview</font>',
                    id:'dash',
                    iconCls:'dashIcon',
                    leaf:true
                 },{
                    text:'Services - <font size=1>Analyze</font>',
                    id:'multiserv',
                    iconCls:'multiservIcon',
                    leaf:true
                 },{
                    text:'Reports - <font size=1>Results</font>',
                    id:'report',
                    iconCls:'reportingIcon',
                    leaf:true
                 },{
                    text:'Options - <font size=1>Settings</font>',
                    id:'options',
                    iconCls:'optionsIcon',
                    leaf:true

                }]

}

这是服务器返回的数据示例

{"id":1,"result":"[\r\n  {\r\n    \"Item1\": \"demo\",\r\n    \"Item2\": 5,\r\n        \"Item3\": 15,\r\n    \"Item4\": \"4308,0\",\r\n    \"Item5\": \"oct. 14, 2012\",\r\n    \"Item6\": \"demo\",\r\n    \"Item7\": \"sept. 14, 2011\"\r\n  }\r\n]"}

这是我的网格之一：

        },

                var detailPanel3 = Ext.getCmp('detailPanel3');
                assetsTpl.overwrite(detailPanel3.body, selectedRecord[0].data);
            }
        }
    }

            flex: 1,

            html: '<br>Please Select an Item to See Additional Details.'
        }]

    }]
}


  ]


});

让我知道你是否需要别的东西

需要注意的是，我检查了商店的长度

var recs=store.getRange(); 
alert(recs.length);

它给出了 48
