Foreign Key to IdentityColumn in a Composite Key

I am trying to use a composite key as descibed in http://www.mindscapehq.com/documentation/lightspeed/Working-with-Legacy-Databases/Using-Composite-Keys (section Foreign Keys That Are Part of a Composite Key)

In my case associated entity has an autoincremented Id.

CREATE TABLE [dbo].[Teams](
    [Id] [int] IDENTITY(1,1) PRIMARY KEY NOT NULL,
    [Category] [varchar](50) NULL
)

CREATE TABLE [dbo].[TeamsLiterals](
    [TeamId] [int] NOT NULL,
    [Lang] [char](2) NOT NULL,
    [Name] [varchar](50) NOT NULL,

CONSTRAINT [PK_TeamsLiterals] PRIMARY KEY CLUSTERED (
    [TeamId] ASC,
    [Lang] ASC
)
)

ForeignKeyFieldAttribute is setted up

...
    #region Relationships

    [ForeignKeyField("Id.TeamId")]
    [ReverseAssociation("TeamsLiterals")]
    private readonly EntityHolder<Team> _team = new EntityHolder<Team>();
...

#endregion

I've got an error during saving changes

Can't find where I'm wrong. Could you give me a clue?

Can you post the code you are using in your ConsoleApplication? I have had a quick test here with this model but I am not running into any issues.

Thanks!
Jeremy

Thank you for quick responce. I've attached the whole project.

Thanks - I have added a fix for the actual issue you are seeing here and this will be available in the next nightly build. That said you will still run into a problem because you are using identity based identifiers for Team and you are using Team.Id when creating your composite key prior to the key having been assigned so this will lead to an FK violation on insert.

To correct this, you should do your insert like this:

  var team = new Team { Id = -1, Category = "Spain" };
  uow.Add(team);

  // Make sure you save Team first to have it assigned an identity value
  uow.SaveChanges();

  var literal = new TeamsLiteral(team.Id, "en") { Name = "Real Madrid" };
  team.TeamsLiterals.Add(literal);

  uow.SaveChanges();
