When I try to save an entity using this mapping, I'm told that the CompositeId class must override "Equals". Which seems like a pain.

Fluent Nhibernate composite key problem

public class PageKeywordMappings : ClassMap<ScrewturnPageKeyword>
    {
        public PageKeywordMappings()
        {
            Table("PageKeyword");
            CompositeId()
                .KeyProperty(m => m.Page)
                .KeyReference(m => m.Keyword)
                .KeyReference(m => m.Namespace);
            Map(m => m.Namespace);
            Map(m => m.Revision);
            Map(m => m.Keyword);
        }
    }
