Using Objects

[ijustwanttoregister]

Hi,

I would like to use an Object in a Zeppelin notebook, something like:

object JsonKey {
  sealed abstract class JsonKey(_name: String) {
    def name = _name
  }
  case object Email extends JsonKey("email")
  case object FacebookId extends JsonKey("facebook_id")
}

however, when later I try to use it in a function definition within a
trait, I get an error:

<console>:45: error: not found: type JsonKey jsonKey: JsonKey,

What is the problem, and is there a workaround for it?

Regards,
