Using future callback inside akka actor

Question

I\'ve found in Akka docs:

When using future callbacks, such as onComplete, onSuccess, and onFailure, inside actors you need to carefully avoid closing ove

I think I would be remiss if I did not mention here that I've made a small utility for circumventing this limitation. In other words, my answer to your question is No, you shouldn't use such an inconvenient workaround, you should use https://github.com/makoConstruct/RequestResponseActor

how does it work?

Basically, behind the futures and the promises, it transmits every query in a Request(id:Int, content:Any), and when it receives Response(id, result) it completes the future that corresponds to id with the value of result. It's also capable of transmitting failures, and as far as I can tell, akka can only register query timeouts. The RequestResponseActor supplies a special implicit execution context to apply to callbacks attached to the futures waiting for a Response message. This blunt execution context ensures they're executed while the Response message is being processed, thus ensuring the Actor has exclusive access to its state when the future's callbacks fire.
