uncaught exception: Ext.Loader is not enabled, so dependencies cannot be resolved dynamically. Missing required class: AM.controller.User
解决方法：
在app.js最上面加上：Ext.Loader.setConfig({ enabled: true });
Ext.Loader.setConfig({ enabled: true });
Ext.application({
name: ‘AM‘,
appFolder: ‘app‘,
launch: function(){
Ext.create(‘Ext.container.Viewport‘, {
layout: ‘fit‘,
items: [
{
xtype: ‘panel‘,
title: ‘用户‘,
html: ‘<font color=blue>用户列表</font>‘
}
]
});
},
controllers: [
‘Users‘
]
});
