Nhibernate Component Mapping : Parent Object null in Value Object while querying from database - nhibernate

Question

I am mapping my value Object Item as component withthe folowing mapping configuration
{
Table("Product");
Not.LazyLoad();
Id(x => x.Id, "id");
Map(x => x.Number, "number");
Map(x => x.Name, "name");
Map(x => x.Description, "description");
Map(x => x.Status, "status");
HasMany(x => x.ItemLines).Component(
m =>
{
m.Map(x => x.ItemId, "itemid");
m.Map(x => x.Qty, "quantity");
}).Table("productitems").KeyColumn("itemid");
}
Class structure
public class ItemLine
{
public Product Product { get; set; }
public Guid ItemId { get; set; }
public int Qty { get; set; }
public ItemLine()
{
}
public ItemLine(Product product, Guid itemId, int qty)
{
Product = product;
ItemId = itemId;
Qty = qty;
}
//Equality and GetHashCode implemented.....
}
I am able to insert data to Database but while retrieving back by Product Id, the Product property in Item Line is null.
Do I need to pass any References in Mapping>
Please help
Thank you,

Ok. Solved by trial and error.
Add m.ParentReference(x => x.Product);
{
Table("Product");
Not.LazyLoad();
Id(x => x.Id, "id");
Map(x => x.Number, "number");
Map(x => x.Name, "name");
Map(x => x.Description, "description");
Map(x => x.Status, "status");
HasMany(x => x.ItemLines).Component(
m =>
{
m.Map(x => x.ItemId, "itemid");
m.Map(x => x.Qty, "quantity");
m.ParentReference(x => x.Product);
}).Table("productitems").KeyColumn("itemid");
}
hope this helps someone.
