ext的grid默认选中行时选中后立即取消问题

我想用ext写一个grid，显示数据时选中其中的一行或几行，发现每次页面打开后grid的复选框都是被选中后立即又取消

给选中操作增加延迟，发现这种情况就没有啦

<html>  
    <head>  
        <meta http-equiv="Content-Type" content="text/html; charset=gbk">  
        <title>ext的grid默认选中问题</title>  
        <link rel="stylesheet" type="text/css" href="../../resources/css/ext-all.css" />  
        <script type="text/javascript" src="../../adapter/ext/ext-base.js"></script>  
        <script type="text/javascript" src="../../ext-all.js"></script>  
        <script type="text/javascript">  
Ext.onReady(function()\{

var sm = new Ext.grid.CheckboxSelectionModel();

var cm = new Ext.grid.ColumnModel(\[  
        new Ext.grid.RowNumberer(),  
        sm,  
        \{header:'编号',dataIndex:'id'\},  
        \{header:'性别',dataIndex:'sex'\},  
        \{header:'名称',dataIndex:'name'\},  
        \{header:'描述',dataIndex:'descn'\}  
    \]);

var data = \[  
        \['1','male','name1','descn1'\],  
        \['2','female','name2','descn2'\],  
        \['3','male','name3','descn3'\],  
        \['4','female','name4','descn4'\],  
        \['5','male','name5','descn5'\]  
    \];

var store = new Ext.data.Store(\{  
        proxy: new Ext.data.MemoryProxy(data),  
        reader: new Ext.data.ArrayReader(\{\}, \[  
            \{name: 'id'\},  
            \{name: 'sex'\},  
            \{name: 'name'\},  
            \{name: 'descn'\}  
        \])

\});

</script>  
    </head>  
    <body>  
        <script type="text/javascript" src="../shared/examples.js"></script>  
        <div id="grid"></div>
