Losing the record ID - fluent-nhibernate

Question

I have a record structure where I have a parent record with many children records. On the same page I will have a couple queries to get all the children.
A later query I will get a record set when I expand it it shows "Proxy". That is fine an all for getting data from the record since everything is generally there. Only problem I have is when I go to grab the record "ID" it is always "0" since it is proxy. This makes it pretty tough when building a dropdown list where I use the record ID as the "selected value". What makes this worse is it is random. So out of a list of 5 items 2 of them will have an ID of "0" because they are proxy.
I can use evict to force it to load at times. However when I am needing lazy load (For Grids) the evict is bad since it kills the lazy load and I can't display the grid contents on the fly.
I am using the following to start my session:
ISession session = FluentSessionManager.SessionFactory.OpenSession();
session.BeginTransaction();
CurrentSessionContext.Bind(session);
I even use ".SetFetchMode("MyTable", Eager)" within my queries and it still shows "Proxy".
Proxy is fine, but I need the record ID. Anyone else run into this and have a simple fix?
I would greatly appreciate some help on this.
Thanks.
Per request, here is the query I am running that will result in Patients.Children having an ID of "0" because it is showing up as "Proxy":
public IList<Patients> GetAllPatients()
{
return FluentSessionManager.GetSession()
.CreateCriteria<Patients>()
.Add(Expression.Eq("IsDeleted", false))
.SetFetchMode("Children", Eager)
.List<Patients>();
}

I have found the silver bullet that fixes the proxy issue where you loose your record id!
I was using ClearCache to take care of the problem. That worked just fine for the first couple layers in the record structure. However when you have a scenario of Parient.Child.AnotherLevel.OneMoreLevel.DownOneMore that would not fix the 4th and 5th levels. This method I came up with does. I also did find it mostly presented itself when I would have one to many followed by many to one mapping. So here is the answer to everyone else out there that is running into the same problem.
Domain Structure:
public class Parent : DomainBase<int>
{
public virtual int ID { get { return base.ID2; } set { base.ID2 = value; } }
public virtual string Name { get; set; }
....
}
DomainBase:
public abstract class DomainBase<Y>, IDomainBase<Y>
{
public virtual Y ID //Everything has an identity Key.
{
get;
set;
}
protected internal virtual Y ID2 // Real identity Key
{
get
{
Y myID = this.ID;
if (typeof(Y).ToString() == "System.Int32")
{
if (int.Parse(this.ID.ToString()) == 0)
{
myID = ReadOnlyID;
}
}
return myID;
}
set
{
this.ID = value;
this.ReadOnlyID = value;
}
}
protected internal virtual Y ReadOnlyID { get; set; } // Real identity Key
}
IDomainBase:
public interface IDomainBase<Y>
{
Y ID { get; set; }
}
Domain Mapping:
public class ParentMap : ClassMap<Parent, int>
{
public ParentMap()
{
Schema("dbo");
Table("Parent");
Id(x => x.ID);
Map(x => x.Name);
....
}
}
ClassMap:
public class ClassMap<TEntityType, TIdType> : FluentNHibernate.Mapping.ClassMap<TEntityType> where TEntityType : DomainBase<TIdType>
{
public ClassMap()
{
Id(x => x.ID, "ID");
Map(x => x.ReadOnlyID, "ID").ReadOnly();
}
}
