Fluent, AutoMappings CompositeID

[Sandor Duis]

I've just spend 3 hours searching reading en trying to get this simple thing to work:

The Class (or Entity)

namespace EntryService.DAL.Domain

    [Serializable]

    public class ClientEntranceInfo 

    {

        public virtual ClientEntranceInfoKey Key { get; set; }

        public virtual int SportSchoolNumber

        {

            get { return Key.SportSchoolNumber; }

            set { Key.SportSchoolNumber = value; }

        }

        public virtual int PassNumber

        {

            get { return Key.PassNumber; }

            set { Key.PassNumber = value; }

        }

        public virtual int ClientNumber

        {

            get { return Key.ClientNumber; }

            set { Key.ClientNumber = value; }

        }

        

        public virtual DateTime EntranceTime { get; set; }

        

        public virtual DateTime UpdateDateTime { get; set; }

        public ClientEntranceInfo()

        {

            Key = new ClientEntranceInfoKey();

        }

    }

The ClientEntranceInfoKey 

namespace EntryService.DAL.CompositeKeys

     [Serializable]

    public class ClientEntranceInfoKey

    {

        public virtual int SportSchoolNumber { get; set; }

        public virtual int PassNumber { get; set; }

        public virtual int ClientNumber { get; set; }

        public ClientEntranceInfoKey()

        {

        }

        public ClientEntranceInfoKey(int sportSchoolNumber, int passNumber, int clientNumber)

        {

            SportSchoolNumber = sportSchoolNumber;

            PassNumber = passNumber;

            ClientNumber = clientNumber;

        }

        public override bool Equals(object obj)

        {

            if (ReferenceEquals(null, obj)) return false;

            if (ReferenceEquals(this, obj)) return true;

            if (obj.GetType() != typeof (ClientEntranceInfoKey)) return false;

            return Equals((ClientEntranceInfoKey) obj);

        }

        public bool Equals(ClientEntranceInfoKey other)

        {

            if (ReferenceEquals(null, other)) return false;

            if (ReferenceEquals(this, other)) return true;

            return other.SportSchoolNumber == SportSchoolNumber && other.PassNumber == PassNumber &&

                   other.ClientNumber == ClientNumber;

        }

        public override int GetHashCode()

        {

            unchecked

            {

                int result = SportSchoolNumber;

                result = (result*397) ^ PassNumber;

                result = (result*397) ^ ClientNumber;

                return result;

            }

        }

    }

The Database Table ClientEntranceInfo (MySQL)

SportSchoolNumber INT(11) PK NN

PassNumber INT(11) PK NN 

ClientNumber INT(11) PK NN

EntranceTime (DATETIME) NN

Very simple I would think.

So.....

var cfg = new MappingsConfiguration();

return Fluently.Configure()

   .Database(MySQLConfiguration.Standard.ConnectionString(ConnString))

   .Mappings(m => m.AutoMappings.Add(AutoMap.AssemblyOf<ClientEntranceInfo>(cfg)

        .Override<ClientEntranceInfo>(map => map.IgnoreProperty(cei => cei.UpdateDateTime))

        .Override<ClientEntranceInfo>(map => map.CompositeId().ComponentCompositeIdentifier

                <ClientEntranceInfoKey>(x => x.Key).KeyProperty(

                     x => x.SportSchoolNumber).KeyProperty(

                     x => x.ClientNumber).KeyProperty(

                     x => x.PassNumber))))

                    .BuildSessionFactory();

            }

With cfg = instance of 

public class MappingsConfiguration : DefaultAutomappingConfiguration

    {

        public override bool ShouldMap(Type type)

        {

            return type.Namespace == "EntryService.DAL.Domain";

        }

    }

gives me this exception:

An association from the table ClientEntranceInfo refers to an unmapped class: EntryService.DAL.CompositeKeys.ClientEntranceInfoKey

Is there somewhere a simple example about this???
