 Hi Endre,

 Thanks for your reply.

 The weird thing is the fact that a String works as message.
 Can you give me a hint where to look for the internationalization
 configuration or how to figure out what is wrong with it?


Unfortunately I don't know, since it is coming from Play. You should
probably ask on the Play mailing list.

-Endre



 You are totally right. It should go back to the sender..

 class ErrorHandlerActor extends Actor {

   val log = Logging(context.system, this)

   def receive: Receive = {
 case e:Error = handleError(e)
 case _ = handleError(Error(UNEXPECTED ERROR!/*,new
 Exception(UNEXPECTED ERROR! The Error Handler received an unknown
 message!)*/))
   }

   def handleError(e:Error) = {
 log.error(e.message)
 sender ! BadRequest(Json.obj(status -Error))
   }
 }

 Looking at the line above, this is somehow related to Play's
 internationalization support, and seems to be something related to its
 configuration. I don't think this error is related to Akka at all.



 I built a case class with the purpose to send it as a Message to an
 Actor:

 package messages

 object ErrorHandlerMessages {
   case class Error (message:String, exception:Exception)
 }

 When I run my application and try to send the message to my actor...:

 class ErrorHandlerActor extends Actor {

   val log = Logging(context.system, this)

   def receive: Receive = {
 case e:Error = handleError(e)
 case _ = handleError(Error(UNEXPECTED ERROR!,new
 Exception(UNEXPECTED ERROR! The Error Handler received an unknown
 message!)))
   }

   def handleError(e:Error):SimpleResult = {
 log.error(e.message,e.exception)
 BadRequest(Json.obj(status -Error, message - e.message))


 Where does this BadRequest instance go? The receive block does not return
 anything and you call it from there... I suspect that you want to somehow
 propagate this object to somewhere.

 -Endre


   }
 }

 ... it throws the error you see above.

 When I change the code a bit so my actor receives a String it works well.
 Can somebody tell me what I am missing?

 Thanks in advance
