C# Dynamic Proxy 2 generate proxy from class with code in constructor ? How to ?

Question

Hello,

I have problem with Dynamic Proxy. I have a class which has logic in constructor. Like this:

public class Document 
{
 public ExtraList<Foo> Possitions {get; set;}

 public Document()
 {
  Possitions = new ExtraList<Foo>();
 }
}

where 'ExtraList' is a special list which can have setted a property of object 'Foo' which have to be only one at list. So next thing is that this object have to be binded to GUI on WinForms. So i wanted ton implement INotifyPropertyChanged by Dynamic Proxy 2 by interceptor. That's cool :)

It looks like this:

 public static T GenerateProxy<T>(T model, SynchronizationContext synchronizationContext, Type type)
{
  var boundModelInterceptor = new BoundModelInterceptor(model, synchronizationContext);
  T modelProxy;

  modelProxy = (T)_proxyGenerator.CreateClassProxy(
    typeof(T),
    new[] { typeof(INotifyPropertyChanged) },
    boundModelInterceptor);

  boundModelInterceptor.PropertyChangedTarget = modelProxy;

  return modelProxy;
}

I have programmed it and now I have a problem that after making class by proxy my list (Possitions) is null but in undelying list it's created. I can not make this list by proxy generator because presenter does not know about domain model logic.

How can I make it work?
