I have a problem with NHibenate. When I run queryover, I get an error "could not resolve property: User.Name of: MegaOnlineChat.Core.Entities.Message".What am I doing wrong? Entity objects public class EntityObject<TId> { public virtual Int32 Id { get; set; } } public class User:EntityObject<Int32> { public virtual String Name { get; set; } public virtual String Password { get; set; } public virtual Boolean Admin { get; set; } public virtual IList<Message> Messages { get; set; } } public class Message:EntityObject<Int32> { public virtual String Text { get; set; } public virtual User User { get; set; } public virtual DateTime Date{ get; set; } } Mapping public class UserMapping:ClassMap<User> { public UserMapping() { Table("Users"); Id(m => m.Id).GeneratedBy.Native(); Map(m => m.Name).Unique().Not.Nullable(); Map(m => m.Admin).Not.Nullable(); Map(m => m.Password).Not.Nullable(); HasMany(m => m.Messages).KeyColumn("User_id"); } } public class MessageMapping:ClassMap<Message> { public MessageMapping() { Table("Messages"); Id(m => m.Id).GeneratedBy.Native(); Map(m => m.Text).Not.Nullable(); Map(m => m.Date).Not.Nullable(); References(m => m.User, "User_id").Not.Nullable(); } } QueryOver NHibernateSession.QueryOver<Message>().Where(x => x.User.Name == name).List<Message>().Last();
