关于修改表单界面的form数据回显问题[急]:checkbox radio combo

如题
对于常规表单通过
form中加入
reader: new Ext.data.JsonReader(
{root:'data'},
    [{name: 'textarea',mapping:'textarea',type:'string'},
     {name: 'mydate',mapping:'mydate',type:'string'},
     {name: 'combo1',mapping:'combo1',type:'string'}
    ]
)

事件中加入
form.getForm().load( {
                url : 'post.jsp?task=2',
                waitMsg : '正在载入数据...',
                success : function(_form,action) {
                    Ext.MessageBox.alert('编辑', '载入成功！');
                },
                failure : function(_form,action) {
                    Ext.MessageBox.alert('编辑', '载入失败');
                }
});
就可以正常的表单反填.
那么对于combo checkbox radio这些种类的控件如何反填值的选中状态?
谢谢
