Fluent Nhibernate: Failed to resolve property

Question

I have a problem with Fluent Nhibernate: error "Could not resolve the MailHeader property of the MailHeader class.

The problem is with the collections inside the MailHeader object, if I delete the collections, the exception will disappear, but I need these collections! Thanks in advance.

public class MailHeader : Entity { public MailHeader() { MailRecipientUsers = new List<MailRecipientUser>(); MailsDeleted = new List<MailDeleted>(); } [Required] public virtual string Subject { get; set; } public virtual IList<MailRecipientUser> MailRecipientUsers { get; protected set; } public virtual IList<MailDeleted> MailsDeleted { get; protected set; } } public class Mail : Entity { public Mail() { Creation = DateTime.Now; MailHeader = new MailHeader(); } [Required] public virtual string BodyText { get; set; } [Required] public virtual MailHeader MailHeader { get; set; } public virtual Mail Parent { get; set; } [Required] public virtual User From { get; set; } public virtual Mail Child { get; set; } [DataType(DataType.Date)] public virtual DateTime Creation { get; set; } //[Required] //public virtual MailType MailType { get; set; } } public class MailRecipientUser : Entity { [Required, DomainSignature] public virtual MailHeader MailHeader { get; set; } [Required, DomainSignature] public virtual User User { get; set; } } public class MailDeleted : Entity { public MailDeleted() { } [DomainSignature,Required] public virtual MailHeader MailHeader { get; set; } [DomainSignature, Required] public virtual User User { get; set; } }

Try creating the setters again in MailHeader.
