Extjs 分析面积图的XML数据时出错

我收到以下解析错误。我知道javascript代码是有效的，因为我已经用静态JsonStore替换了xml集成。你能看出我做错了什么吗

提前感谢您的建议

Error: Problem parsing d="L790,518.887301636L120,518.887301636Z" results-graph3.htm:1111
Error: Problem parsing d="Z" 

XML文件：

<?xml version="1.0" encoding="utf-8"?>
<fundGrowthData>
    <growthData>
        <Year>1991</Year>
        <asOfDate>December 31, 1991</asOfDate>
        <Dividends>10000</Dividends>
        <Distribution>10000</Distribution>
    </growthData>
    <growthData>
        <Year>1992</Year>
        <asOfDate>December 31, 1992</asOfDate>
        <Dividends>10655</Dividends>
        <Distribution>10740</Distribution>
    </growthData>
    <growthData>
        <Year>1993</Year>
        <asOfDate>December 31, 1993</asOfDate>
        <Dividends>12146</Dividends>
        <Distribution>12297</Distribution>
    </growthData>
</fundGrowthData>

因为默认情况下xml是字符串，所以我必须将类型属性添加到Ext.data.Store

var store = Ext.create('Ext.data.Store',{
    autoLoad: true,
    fields: [
        {name : "Year", type: "int"},
        {name : "Dividends", type: "int"},
        {name : "Distribution", type: "int"}
        ],
    proxy: {
        type: 'ajax',
        url: 'pathToXml',
        reader: {
            type: 'xml',
            record: 'growthData'
        }
    }
});

var store = Ext.create('Ext.data.Store',{
    autoLoad: true,
    fields: [
        {name : "Year", type: "int"},
        {name : "Dividends", type: "int"},
        {name : "Distribution", type: "int"}
        ],
    proxy: {
        type: 'ajax',
        url: 'pathToXml',
        reader: {
            type: 'xml',
            record: 'growthData'
        }
    }
});
