[kepler-dev] On Multi-outputs of Web Service actor

[Ilkay Altintas]

Jianting,

I tested it with a web service with multiple output parts  when I  
implemented the actor 2 years ago. It was working then.  Maybe  
something has changed since then. This feature wasn't used as nobody  
actually used the actor to handle multiple outputs.

Will you create a web service with multiple outputs? We can test  it  
with it.

Thanks,
