Thanks for the reply! btw, regarding to mixing trait, I happened to have a quick question: (which is actually a scala question rather than akka)
can I do dynamic mixing with some reflection utils like: def mixAndCreateInstance(class:Class[?], traits: Seq[Class[?]]) I may have some logic to control which trait to mixing at runtime, like new MyClass(myParam) with traitA1 with traitB1) new MyClass(myParam) with traitA1 with traitB2) new MyClass(myParam) with traitA2 with traitB1) new MyClass(myParam) with traitA2 with traitB2) If there's some dynamic way, I think above code might be simplified.
