NHibernate returning duplicate object in child collections when using Fetch

Question

When doing a query like this (using Nhibernate 2.1.2):

 ICriteria criteria = session.CreateCriteria()
                .SetFetchMode(\"ChildColl         


        

Answer 1

Try using Futures:

ICriteria criteriaFuture1
    = session.CreateCriteria()
        .SetFetchMode("ChildCollection1", FetchMode.Eager)
        .Add(Restrictions.IdEq(id))
        .SetResultTransformer(Transformers.DistinctRootEntity)
        .FutureValue();
 ICriteria criteriaFuture2
    = session.CreateCriteria()
        .SetFetchMode("ChildCollection2", FetchMode.Eager)
        .Add(Restrictions.IdEq(id))
        .SetResultTransformer(Transformers.DistinctRootEntity)
        .FutureValue();

 return criteriaFuture1.Value;
