Thanks Fabio, but what do you mean with > this is the line we have on our sources
On https://nhibernate.svn.sourceforge.net/svnroot/nhibernate/branches/1.2.x/nhibernate/src/NHibernate/Impl/CollectionKey.cs I still find the line "return keyType.Equals(key, that.key) && Equals(role, that.role);" Is your suggestion kind of backport from 2.0? -Chris
