CRUD Update, changing entity relationship with dropdown using ASP.NET MVC 2, and NHibernate

Question

I'm running into a few problems with CRUD Update (Edit) scenarios where an entity relationship is altered via drop down list of possible entities, using ASP.NET MVC and NHibernate. Probably I am just doing something stupid, so I was wondering if someone could give me a quick example of how this should be done, as I haven't been able to find many examples on the web. (There's nothing like this in NerdDinner for example)

So using an arbitrarily simple model:

Public Class Person
{
   int Id { get; set;}
   string Name { get; set}
   Person Buddy { get; set}
}

Could you give me an example (or link to an example) of the 'Update' Crud view and action(s) in this scenario?

• Don't worry about repository code
• For the sake of comparison with some existing code, it would be helpful if the example used formcollection (I know this is not ideal).

Thank you!

You can try to look at Sharp architecture. They have a Northwind sample with EmployeesController and TransferValues method. There update is shown for nested entities
