Hello!

NHibernate gives me a strange cast exception. The message of the exception is: "Unable to cast object of type 'Iesi.Collections.HashedSet' to type 'System.Collections.IList'.". The stack trace is:
at NHibernate.Type.PersistentCollectionType.Copy(Object original, Object target, ISessionImplementor session, Object owner, IDictionary copiedAlready)
at NHibernate.Type.TypeFactory.Copy(Object[] original, Object[] target, IType[] types, ISessionImplementor session, Object owner, IDictionary copiedAlready)
at NHibernate.Impl.SessionImpl.DoCopy(Object obj, Object id, IDictionary copiedAlready)
at NHibernate.Impl.SessionImpl.SaveOrUpdateCopy(Object obj)
at "Here goes my own function invocation".

Do some of you know how to overcome this difficulty?


Best regards,

It looks like the solution done for NH-293 in order to support maps does not work for sets as well.

I would like very much if this would work. Should I do something in order to improve the likelyhood it will be fixed?

Best regards,

Are you using the CVS version? The bug is fixed in CVS, and it will be part of the 0.9 release.
