Where is field parameter being used? Otherwise, can we just delete it?

[dsinclair, 2016/09/22 13:16:45]

Done. It looks like the stranger issue is that while we'd pass the field getting
or losing focus into here, the public api would drop the field, which is really
weird.

Removing it from here, we can bring back later if it's needed.
