Fred, You made me think I might have run the migration prematurely. So far, all examples in the book have worked perfectly (I can't say that for many books!) so it might be a layer 8 issue.... I don't remember running it before I updated the migration file, but it's possible. If the t.references should work, I'm happy to know that at least. I'll go back and run through another test to see if it gets the same results.
