Castle Active Record - one to many relationship

Question

I try create many to relationship one to many in Active record.

[ActiveRecord("Users")]
public class User : ActiveRecordBase<User>
{
    private IList<PhotoAlbum> _albums = new List<PhotoAlbum>();

    [PrimaryKey]
    public virtual int UserId { get; set; }

    [BelongsTo("ProfilId")]
    public virtual Profil Profil { get; set; }

    [HasMany(Inverse = false,Cascade = ManyRelationCascadeEnum.Delete)]
    public IList<PhotoAlbum> Album
    {
        get { return _albums; }
        set { _albums = value; }
    }

    [Property]
    public virtual string Nick { get; set; }

}

[ActiveRecord("Profiles")]
public class Profil : ActiveRecordBase<Profil>
{
    [PrimaryKey]
    public int ProfilId { get; set; }

    [Property]
    public int Age { get; set; }
    [Property]
    public int Sex { get; set; }
    [Property]
    public string Region { get; set; }
    [Property]
    public string Town { get; set; }
    [Property]
    public bool WithPhoto { get; set; }
    [Property]
    public bool HasPhotoAlbum { get; set; }
}

[ActiveRecord("PhotoAlbums")]
public class PhotoAlbum : ActiveRecordBase<PhotoAlbum>
{
    [PrimaryKey]
    public int PhotoAlbumId { get; set; }

    [Property]
    public string Name { get; set; }
    [Property]
    public int NumberOfPhoto { get; set; }
}

I am using sample from http://www.castleproject.org/activerecord/gettingstarted/relations.html

it finished with this error:

ActiveRecord tried to infer details about the relation User.Album but it could not find a 'BelongsTo' mapped property in the target type

StrackTrace:

SAMPLE_1.PhotoAlbum

I think problem is here:

    [HasMany(Inverse = false,Cascade = ManyRelationCascadeEnum.Delete)]
    public IList<PhotoAlbum> Album
    {
        get { return _albums; }
        set { _albums = value; }
    }

If I omitted this property / relationship it works good.

Assuming one profile has many photo albums, your PhotoAlbum class is missing a property:

[BelongsTo("ProfileId")]
public Profile Profile { get; set; }
