PersistentActor cannot invoke persist handler in Future onComplete - scala

Question

I am pretty new using PersistentActor ,
when I try to call updateState from a future onComplete, fails , nothing happanes , tried to debug it and I do get to the persist call but not into the updateState
trait Event
case class Cmd(data: String)
case class Evt(data: String) extends Event
class BarActor extends PersistentActor{
implicit val system = context.system
implicit val executionContext = system.dispatcher
def updateState(event: Evt): Unit ={
println("Updating state")
state = state.updated(event)
sender() ! state
}
def timeout(implicit ec: ExecutionContext) =
akka.pattern.after(duration = 2 seconds, using = system.scheduler)(Future.failed(new TimeoutException("Got timed out!")))
val receiveCommand: Receive = {
case Cmd(data) =>
def anotherFuture(i: Int)(implicit system: ActorSystem) = {
val realF = Future {
i % 2 match {
case 0 =>
Thread.sleep(100)
case _ =>
Thread.sleep(500)
}
i
}
Future.firstCompletedOf(Seq(realF, timeout))
.recover {
case _ => -1
}
}
val res = (1 to 10).map(anotherFuture(_))
val list = Future.sequence(res)
list.onComplete{
case _ =>
persist(Evt("testing"))(updateState)
}
}
}

Answer 1

You could try this:
list.onComplete {
case _ => self ! Evt("testing")
}
And add this to receiveCommand
case evt: Evt =>
persist(Evt("testing"))(updateStates)
