Thanks for your reply Fabio. I guess that means I have to use HBM rather
than FluentNHibernate as I can't find support for IdBag.

Hello,
I've got a user and a place entity, and a relationship mapped between
them using a 'UserPlace' entity (A user can belong to many places).
The mapping, with FluentNH, is below. This works fine, but I've
noticed that every time I modify a User's UserPlace (setting a place
as default or selected) the entire collection of UserPlace is first
deleted from the database, and then reinserted. I assume it's because
NHibernate doesn't know enough about what distinguishes one row from
another, so how can I change my mapping to prevent a complete deletion
and re-insertion of all rows?
public class UserMap : ClassMap
{
HasMany(x => x.Neighbourhood)
.Component(c =>
{
c.Map(x => x.IsDefault).Not.Nullable();
c.Map(x => x.Selected).Not.Nullable().Default("0");
c.References(x => x.Place).Fetch.Join();
}
).Not.LazyLoad().Cascade.SaveUpdate();
}
