我有一个包含所有项目详细信息的网格。 此网格有自己的控制器，型号，商店。当我双击网格时，它会将ID传递给我的服务器端。
根据传递的id，我对我的数据库执行一些查询，然后以JSON格式将数据返回给客户端。基于成功的响应，我展示了另一个窗口，其中包含从服务器返回给客户端的所有数据。
但主要问题是窗口弹出窗口不包含更新的数据。首次单击正确传递的网格ID并正确创建窗口时的方法。 现在关闭弹出窗口后，当我点击网格时，会弹出窗口弹出窗口，但其中包含的数据不是更新数据。
那么我该怎么做才能根据传递的网格ID向我显示更新的数据。
双击网格我执行以下代码
editProject: function(grid, record) {
console.log('Double clicked on ' + record.get('id'));
Ext.Ajax.request({
url : 'projecttask/GetprojectTasks.action',
method: 'GET',
params: {'id':record.get('id')},
scope: this, // add the scope as the controller
success : function(response, opts) {
this.getProjectGanttwindow().show();
},
failure : function(response, opts) {
alert('Export file failed!')
}
});
我的ProjectGanttWindow代码在
