[Lift] Re: NULLable MappedForeignKey

[David Pollak]

All MappedForeignKeys are Nullable.
If you've got
object theUser extends MappedLongForeignKey(this, User)

You can set the field to null with:

theUser(Empty)

Does that help?

Just to check -- are you familiar with the difference between option
types and null references in scala? It's an important distinction and
it's very important with Lift.
