Is it possible to search for details records, based on a property of a master class.

E.G.

Code:

Class A //Master
{ Id, NameA, CollectionOfB }
Class B // Detail
{ Id, NameB, RefToA }

IList result = session.CreateCriteria(typeof(B))
      .Add(Expression.Eq("RefToA.NameA","SearchNameA")
      .List();

Something like section 12.4 of the Hibernate documentation at
http://www.hibernate.org/hib_docs/refer ... teria.html

Thanks,
Geert

I don't think this will work, current ICriteria implementation can't handle references to other entities. But try it, maybe I'm thinking too bad of NHibernate :)
