NullPointerException when querying an entity's transient val #109

Closed alcarvalho closed 10 years ago

alcarvalho commented 10 years ago

I have the following entities:

trait User extends Entity {
  @transient val userLogin: String
  val email: String
  val passwordHash: String
  val name: String
}

case class Specialist(email: String, @transient password: String, name: String, cpf: String) extends User {
  @transient override val userLogin = email
  override val passwordHash = User.hashPassword(userLogin, password)
}

// And the following query:
object User {
  def authenticate(login: String, password: String)(implicit ctx: TransactionalExecutionContext): Future[User] = {
    asyncSelect[User].where(_.userLogin :== login, _.passwordHash :== hashPassword(login, password)) map {
      case List(user) => user
      case _ => throw new AuthenticationError
    }
  }
}

When I use the "authenticate" function from User object, I get the following exception, only if I use a non memory persistence. In this case, postgresql-async:
