Ext 中RadioGroup 监听事件 为什么只执行一次

正确做法:

{xtype:'radiogroup',hideLabel:false,name:'material.isProduceMaterial',fieldLabel:'是否为生产原料',

items : [

   {

boxLabel:'是',

name:'material.isProduceMaterial',inputValue:'Y',checked: true,

listeners:{'check':function(checkbox,checked){

if(checked){

Ext.getCmp("defaultWarningId").setDisabled(false);

var data = gridPanel.getSelectionModel().getSelections()[0].data;

Ext.getCmp("defaultWarningId").setValue(data.defaultWarning);

};

}}

},

{

boxLabel:'否',

name:'material.isProduceMaterial',inputValue:'N',

listeners:{'check':function(checkbox,checked){

if(checked){

Ext.getCmp("defaultWarningId").setDisabled(true);

Ext.getCmp("defaultWarningId").setValue("0");

};

}}

}

]

}}
