Windows Store应用程序/ Metro应用程序：ListView数据绑定错误

我正在处理Windows应用程序/ Metro UI应用程序，它从AppSettings获取数据并在ListView中绑定这些数据。这是data.jsWindows Store应用程序/ Metro应用程序：ListView数据绑定错误

(function() { 
    "use strict"; 

    var dataSource = new Array(); 
    var dataList = new WinJS.Binding.List(); 

    var appData = Windows.Storage.ApplicationData.current; 
    var roamingSettings = appData.localSettings; 
    var json = roamingSettings.values["reminderList"]; 
    if (json != undefined) { 
     dataSource = JSON.parse(json); 


     for (var i in dataSource) { 
      var rem = dataSource[i]; 
      dataList.push(rem); 
     } 

    } 
    // Create a namespace to make the data publicly 
    // accessible. 
    var publicMembers = 
     { 
      itemList: dataList 
     }; 
    WinJS.Namespace.define("MyData", publicMembers); 
})();

的代码，这是我的ListView使用的代码。

<div id="basicListView" data-win-control="WinJS.UI.ListView" 
      data-win-options="{ itemDataSource : MyData.itemList.dataSource, itemTemplate:select('#mediumListIconTextTemplate') }">

但是，当有在存储一个项目，它显示了在ListView中不确定。当AppSettings中有多个项目时，它会给我下面的错误。

      }] 
     ], 
     "_isException": false,

}

任何人都可以请我指出一个解决方案。

您的模板mediumListIconTextTemplate是什么样子的？它与您用来构建数据列表的JSON对象相匹配吗？我怀疑它是。

另外当你说错误被提出时，你是否也可以提供堆栈跟踪？

如果您发布了示例JSON以及mediumListIconTextTemplate的定义，分析问题将会有所帮助。
