Ext中添加多个FCKeditor

最近在应用ext,但是在应用到ext中自带的htmleditor时，在粘贴word文档时出现问题，现在修改方案，将htmleditor换为FCKeditor，但是在同一个页面应用到多个时，也会出现问题，现在写了一个小例子，是tab页中有2个fckeditor，这个例子包括了取值及赋值问题

Ext.onReady(function(){

var fckeditorFormPanel = new Ext.FormPanel({
        labelWidth: 75,
        url:'',
        frame:true,
        title: 'fckeditor Form',
        bodyStyle:'padding:5px 5px 0',
        width: 850,
        height:450,
        defaultType: 'textfield',

        items: [{
            xtype:'textarea',
            fieldLabel:'编辑',
labelSeparator:'：',
id:'code',
name:'code',
            height:200,
width:300
                }
        ],
        buttons: [{
            text: 'Save',
            handler:function(){
        }
        },{
            text: 'Cancel'
        }]
    });


var fckPanel = new Ext.FormPanel({
        labelWidth: 75,
        url:'',
        frame:true,
        title: 'fckPanel',
        bodyStyle:'padding:5px 5px 0',
        width: 850,
        height:450,
        defaultType: 'textfield',

        items: [{
            xtype:'textarea',
            fieldLabel:'编辑',
labelSeparator:'：',
id:'sss',

                }
        ],
        buttons: [{

            handler:function(){
       
        }
        },{
            text: 'Cancel'
        }]
    }); 
//fckeditorFormPanel.render(document.body);
