Hi Moon,
here is a simplified example. Both the object and the trait are defined in
the same section.
```
object JsonKey {
sealed abstract class JsonKey(_name: String) {
def name = _name
}
case object Email extends JsonKey("email")
case object FacebookId extends JsonKey("facebook_id")
}
trait EventProcessor extends Serializable {
def extractId(id: Int,
jsonKey: JsonKey,
map: java.util.Map[String,AnyVal]): Option[Int] = {
//Business logic (not relevant for the question)
None
}
}
```
Output:
```
defined module JsonKey <console>:22: error: not found: type JsonKey
jsonKey: JsonKey, ^
```
Regards,
Alexander Fedulov
