Hibernate version: 1.2.0 Beta 2

How do I serialize an object with collections. When I set the collection as a generic.ilist<> xmlserializer states it can not serialize interfaces. When I set the collection as generic.list<>, nhibernate can not cast PersistentGenericBag to generic.list<>.

Class:

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

namespace RateChart.DataAccess.Entities
{
[Serializable()]
public class RateChartRequest
{
private int _RateChartRequestID;
public virtual int RateChartRequestID
{
get { return _RateChartRequestID; }
set { _RateChartRequestID = value; }
}

private string _RequestStatus;
public virtual string RequestStatus
{
get { return _RequestStatus; }
set { _RequestStatus = value; }
}

private bool _EmailRateChart;
public virtual bool EmailRateChart
{
get { return _EmailRateChart; }
set { _EmailRateChart = value; }
}

private bool _PrintRateChart;
public virtual bool PrintRateChart
{
get { return _PrintRateChart; }
set { _PrintRateChart = value; }
}

private bool _SampleRateChart;
public virtual bool SampleRateChart
{
get { return _SampleRateChart; }
set { _SampleRateChart = value; }
}

private int _CountRateBooks;
public virtual int CountRateBooks
{
get { return _CountRateBooks; }
set { _CountRateBooks = value; }
}

private int _CountRetailBooks;
public virtual int CountRetailBooks
{
get { return _CountRetailBooks; }
set { _CountRetailBooks = value; }
}

private Entities.Dealer _Dealer;
public virtual Dealer Dealer
{
get { return _Dealer; }
set { _Dealer = value; }
}

private Entities.ProductType _ProductType;
public virtual Entities.ProductType ProductType
{
get { return _ProductType; }
set { _ProductType = value; }
}

private List<Entities.RateChartRequestLoad> _RequestLoads;
[XmlArray("RequestLoads"), XmlArrayItem("RateChartRequestLoad", typeof(Entities.RateChartRequestLoad))]
public virtual List<Entities.RateChartRequestLoad> RequestLoads
{
get { return _RequestLoads; }
set { _RequestLoads = value; }
}

private List<RateChartRequestOptionItem> _RateChartRequestOptionItems;
[XmlArray("RateChartRequestOptionItems"), XmlArrayItem("RateChartRequestOptionItem", typeof(Entities.RateChartRequestOptionItem))]
public virtual List<RateChartRequestOptionItem> RateChartRequestOptionItems
{
get { return _RateChartRequestOptionItems; }
set { _RateChartRequestOptionItems = value; }
}

private Entities.Product _Product;
public virtual Entities.Product Product
{
get { return _Product; }
set { _Product = value; }
}

}
}
