XAF中如何实现Action创建一个可以编辑外连接对象的detail

在系统中有时候我们希望实现这样的创建操作，通过主数据创建一个关联表的对象，比如，通过库存表创建一个出入库单的对象并弹出一个窗体编辑给对象，在xaf中可以使用如下的代码实现:
using System;
using System.ComponentModel;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.Persistent.Base;
using DevExpress.ExpressApp.SystemModule;
namespace Tes.Module.INVE.Controllers
{
public partial class InveActionContriller : ViewController
{
private DetailView createdDetailView;
//private InveActionContriller newController;
public InveActionContriller()
{
InitializeComponent();
RegisterActions(components);
//this.TargetViewType = ViewType.ListView;
//this.TargetViewNesting = Nesting.Nested;
//this.TargetObjectType = typeof(Dy_Inventory);

}
private void actionCreateAdm_Execute(object sender, SimpleActionExecuteEventArgs e)
{

//Find an existing object.

//Contact obj = os.FindObject<Contact>(CriteriaOperator.Parse("FirstName=?", "My Contact"));

//Or create a new object.
Contact obj = View.ObjectSpace.CreateObject<Contact>();

obj.Dy_Materials = (Dy_Inventory)e.CurrentObject;

//Save the changes if necessary.

View.ObjectSpace.CommitChanges();
IObjectSpace os = Application.CreateObjectSpace();

e.ShowViewParameters.CreatedView = Application.CreateDetailView(os, os.GetObject(obj));
//os = os.GetObject(obj);
os.SetModified(os.GetObject(obj));
//Specify various display settings.

e.ShowViewParameters.TargetWindow = TargetWindow.NewModalWindow;

e.ShowViewParameters.Context = TemplateContext.NestedFrame;

e.ShowViewParameters.CreateAllControllers = true;

//Provide standard dialog window functionality.

DialogController dc = Application.CreateController<DialogController>();

e.ShowViewParameters.Controllers.Add(dc);

View.ObjectSpace.Refresh();

}
}
}
