我使用网格面板。当我选择网格中的行时，会得到以下结果：

• 如果我在文件中提交表格。body'一切正常，表单字段已填充。
• 如果我在“窗口”面板中启动相同的“窗体”，则“窗体”字段为空。
• 当我同时使用这两者时，“文档”中呈现的Form。body”关闭，并填充窗口中的Form字段。

我犯错误的地方。

// Grip panel part
sm: new Ext.grid.RowSelectionModel({
        singleSelect: true,
        listeners: {
                    rowselect: function(sm, index, record) {deleteWindow.show();}
                   }
        })  
// End Grid panel part      

var myForm = new Ext.form.FormPanel({
        title:"Basic Form",
        width:425,
        frame:true,
        items: [
            new Ext.form.TextField({
                id:"to",
                fieldLabel:"To",
                width:275,
                allowBlank:false,
                blankText:"Please enter a to address",
                     readOnly: true
            }),
            new Ext.form.TextField({
                id:"subject",
                fieldLabel:"Subject",
                width:275,
                allowBlank:false,
                blankText:"Please enter a subject address",
                readOnly: true
            }),
        ],
        buttons: [
            {text:"Cancel"},
            {text:"Save"}
        ]
    });

var deleteWindow = new Ext.Window({
        id: 'id_deleteWindow',
        title: 'Delete',
        closable:true,
        width: 750,
        height:     380,
        plain:true,
        layout: 'fit',
        items: myForm
});

var id_test = 2;  // This is only for this problem

//myForm.render(document.body);  // When using this code everything is ok, and form fields are filled

myForm.getForm().load({
                url:'ggg.php',
                params:{
                        id: id_test
                         }
});

JSON数据

{success:true,results:[{"id_test":"1","to":"a","subject":"aa"}]}
