Ext.tab.Panel 组件代码：
Ext.define("myapp.view.application.TabMain", {

extend : "Ext.tab.Panel", xtype : "tabmainT", id : "tabmainT", config : { tabBarPosition : 'bottom', defaults : { layout : 'fit' }, tabBar : { hidden : true }, items : [ { numb : 0, iconCls : "tabpostion",//指定背景图片样式类 scrollable : true, items : [ { docked : 'top', items : [ { xtype : "panel", html : '第一个HTML', width : '100%' } ] } ] }, { numb: 1, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第二个HTML', width:'100%' }] } ] },{ numb: 2, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第三个HTML', width:'100%' }] } ] } , { numb: 3, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第四个HTML', width:'100%' }] } ] } , { numb: 4, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第五个HTML', width:'100%' }] } ] } , { numb: 5, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第六个HTML', width:'100%' }] } ] }] }

});

当我把{

numb: X, iconCls: "tabpostion", scrollable: true, items:[{ docked:'top', items : [{ xtype : "panel", html : '第六个HTML', width:'100%' }] } ] }

的html代码去掉 xtype指定指定一个panel 然后就报错：

panel代码 Ext.define('myapp.view.application.Home',{

extend : 'Ext.Panel', xtype:'home', id:'home', config : { layout:{ type:'vbox', align:'stretch' //子组件将填满整个宽度 }, items:[ { xtype:'tabmainT', numb:0, flex:13, }, { flex:1, docked:'bottom', html:'

});
求大神帮忙告诉我哪里错了，如何改正
