Using Automapper to make full copy of an object with IList properties

So I need to make copies of objects. I have a model here "place" that has a IList HasAndBelongsToMany Property that is being a pain. I need to take the field property and copy it too but it copies the reference only. Here is what i have

public class place : ActiveRecordBase<place>
{
    public place() {  }

    private int place_id;
    [PrimaryKey("place_id")]
    virtual public int id
    {
        get { return place_id; }
        set { place_id = value; }
    }
    private IList<fields> Fields;
    [HasAndBelongsToMany(typeof(fields), Lazy = true, Table = "place_to_fields", ColumnKey = "place_id", ColumnRef = "field_id", NotFoundBehaviour = NotFoundBehaviour.Ignore, Cascade = ManyRelationCascadeEnum.AllDeleteOrphan)]
    virtual public IList<fields> field
    {
        get { return Fields; }
        set { Fields = value; }
    }
}

And use automapper like this

place org = ActiveRecordBase<place>.Find(id);

Mapper.Reset();
Mapper.CreateMap<place, place>().ForMember(dest => dest.id, o => o.Ignore())
                                .ForMember(dest => dest.field, o => o.Ignore())
                                ; 
place copy = new place();
Mapper.Map(org, copy);

copy.SaveAndFlush();

Which works because i'm skiping the field. What i was hoping for was something more like:

Mapper.CreateMap<place, place>().ForMember(dest => dest.id, o => o.Ignore())
                                .ForMember(dest => dest.field.id, o => o.Ignore())
                                ;

See the first line with .ForMember(dest => dest.id, o => o.Ignore()) is so that I don't copy the reference id for the place object. I need to do the same for the place property field. I need to ignore the id's and make new entries with the same values on the rest of its properties

You need to create mapping for field type and add "Ignore" option for field's id like you've alredy done for place type.

Mapper.CreateMap<fields, fields>().ForMember(dest => dest.id, o => o.Ignore());
Mapper.CreateMap<place, place>().ForMember(dest => dest.id, o => o.Ignore());
