This code fails with session-based non-persistent classes when Refresh action is called:

"The error occurred:
Type:       SessionMixingException
Message:    The 'Example.Module.MyNonPersistentObject' object belongs to a different session."

void application_CustomProcessShortcut(object sender, CustomProcessShortcutEventArgs e)
{
   if (e.Shortcut.ViewId == "MyNonPersistentObject_DetailView")
   {
       IObjectSpace objectSpace = Application.CreateObjectSpace();
       e.View = Application.CreateDetailView(objectSpace, objectSpace.CreateObject<MyNonPersistentObject>(), true);
       e.Handled = true;
   }
}

How to solve it?
