});
var myStore = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'ajax',
url: 'user.txt',

type: 'json',

});
Ext.create('Ext.view.View', {
width:200,
store: myStore,
tpl: ['<div>',
'<tpl for=".">',
'<div>',
'<div class="nrm_menu_banner">{name}</div>',
'<tpl for="childrens">',
'<div class="nrm_menu_content">{name}</div>',
'</tpl>',
'</div>',
'</tpl>',
'</div>'
],
itemSelector: 'div.nrm_menu_content',
overItemCls: 'hover',
trackOver: true,
renderTo: Ext.getBody()
});
}
现在遇到的问题是，如果itemSelector设置为 'div.nrm_menu_content',则报
Uncaught TypeError: Cannot read property 'internalId' of undefined错误，why???
