[akka-user] mixing FSM and akka-persistence

hi all, I am trying to do something like: class MyFSM extends Processor with FSM and at first it seems that it does not work properly. Is it possible to use Processor and FSM together? Thanks, Nicola -- >> Read the docs: http://akka.io/docs/ >> Check the FAQ:

Re: [akka-user] mixing FSM and akka-persistence

Hi, I can also confirm that this is working - we are using persistence for recovery of our fsm's (storing initialization messages and do snapshots when stopping/hibernating them) Cheers, Christian Am Samstag, 3. Mai 2014 17:20:46 UTC+2 schrieb Konrad Malawski: > > Is it possible to use Process

Hi Christian, Do you have a small reproducible test case that exposes the problem? If you do, please share so we can look into the possible issue. -Endre On Sun, May 4, 2014 at 2:07 PM, Nicola Piccinini wrote: > Yes, http://doc.akka.io/docs/akka/snapshot/scala/persistence. >> html#state-machin

Re: [akka-user] mixing FSM and akka-persistence

hi, I am Nicola (not Christian), I created a github repo for you: https://github.com/pic/akkaTheHutt you have three classes: FiniteStateMachine ( no persistence, extends Actor ) AlmostPersistentFSM ( extends Processor but no use of Persistent ) PersistentFSM ( persistence ) The only differenc

Re: [akka-user] mixing FSM and akka-persistence

Hi Nicola, thanks for providing the sample project, I tried it out and the problem is that the FSM never processes a single message when instantiated in a TestFSMRef. It works fine if you change it to system.actorOf(Props(new ...)) and then rely on SubscribeTransitionCallBack to monitor the progre

thanks Roland for taking care of it. What about the second part of my email concerning the problem I have recovering the PersistentFSM: -- There are also three objects that you can run FiniteStateMachineSpes -> Main AlmostPersistentFSMSpec

Re: [akka-user] mixing FSM and akka-persistence

Hi Nicola, PersistentMain doesn't work as you expect because the sequence of messages during "normal" operation and during replay differs: - during normal operation your FSM receives non-persistent StateTimeout events and persistent Done messages. Both are necessary for your FSM to make the

Re: [akka-user] mixing FSM and akka-persistence

Hi, I think I stumbled over a potential pitfall when using a Processor with a FSM - in case I have a RecoveryFailure the FSM will "handle" the message via default handling. If I have read the code correctly, the Processor will stay in a state where it stashes incoming messages forever - which w
