That is not going to work. Let's say that the confirmation message is lost. Then AtLeastOnceDelivery will resend it to the path of the PromiseActorRef (created by ask), but that is already completed and the resent message will go to deadLetters, and be retried again. Would it be possible to implement it without ask? > To be honest, I'm not sure If what I'm doing is weird somehow because of the > temporary actor from AskSupport (I'm experimenting/prototyping).

Is this by design? I don't think we have thought of replying to an ask via an actor selection, because we have not thought of a use case where it would be needed. > > Ferdinand > -- > >>>>>>>>>> Read the docs: http://akka.io/docs/ > >>>>>>>>>> Check the FAQ: > >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html > >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user > --- > You received this message because you are subscribed to the Google Groups > "Akka User List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to akka-user+unsubscr...@googlegroups.com. > To post to this group, send email to akka-user@googlegroups.com. > Visit this group at http://groups.google.com/group/akka-user. > For more options, visit https://groups.google.com/d/optout. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
