Hi there, 

i am having trouble with making akka recognize an UnMarshaller, for 
improved formatting i have post my question in 
stackoverflow 
http://stackoverflow.com/questions/40469370/missing-fromrequestunmarshallerentity-on-akka-post-route

in summary i am getting the error 

could not find implicit value for parameter um: akka.http.scaladsl.
unmarshalling.FromRequestUnmarshaller

i am originally using code from 
http://www.cakesolutions.net/teamblogs/message-formats-marshallers-and-code-quality

the UnMarshaller there does not seem to get recognised, 

I was able to solve the issue just by introducing a specialised 
UnMarshaller in scope. 

implicit val um:Unmarshaller[HttpEntity, PropertyEntity] = {
    Unmarshaller.byteStringUnmarshaller.mapWithCharset { (data, charset) =>
        val charBuffer = Unmarshaller.bestUnmarshallingCharsetFor(data)
        
JsonFormat.fromJsonString(data.decodeString(charBuffer.nioCharset().name()))(PropertyEntity)
        
/*PropertyEntity.parseFrom(CodedInputStream.newInstance(data.asByteBuffer))*/
    }
  }



This solutions has 2 issues, 


1. i need to provide an unmarshaller for each entity i use, these entities 
are generated from ScalaPB, i tried using their base class, but i am not 
sure how to map it to a specific class upon deserialisation
2. not sure how to write the condition to use the different unmarshaller 
based on request headers.
