[akka-user] invalid materialized value

[EXTERNAL Wachter Stefan (Keybird IT Consulting und Vetriebs GmbH, INST-ICM/BSV-BS)]

Hi all,

the following line of code


val ((pub, mat), sub) = 
TestSource.probe[Int].viaMat(Flow[Int])(Keep.both).toMat(TestSink.probe)(Keep.both).run()

throws a ClassCastException:


java.lang.ClassCastException: akka.stream.testkit.TestPublisher$Probe cannot be 
cast to scala.Tuple2

it seems that the viaMat(...)(Keep.both) does not what it promises.

Mit freundlichen Grüßen / Best regards
