Problems when sending client acks

Hi,

I recently timeboxed an exercise to try out play-socketio with a client callback. I attempted to modify the simple Chat sample app using the "Handling Acks" section of docs. I may be using the library wrong, or the client lib wrong, but what I observed is that the first event I emitted was ack'd properly in the client callback, but no subsequent event worked. I also expected the response I sent the callback to show up in the namespaced stream I setup, but I did not see it there.

These are the changes I made to the sample app:
https://github.com/playframework/play-socket.io/compare/master...seglo:master

https://github.com/seglo/play-socket.io/blob/master/samples/scala/chat/app/chat/ChatEngine.scala

Any assistance would be appreciated.

Thanks,
Sean

Read the "Handling Acks" section in docs/ScalaSocketIO.md and inspect the changes and sample file at samples/scala/chat/app/chat/ChatEngine.scala. Reproduce the Chat sample behavior using the linked comparison, then verify whether subsequent emitted events receive client callbacks and whether the callback response appears in the configured namespaced stream.
