Hello,

when playing with Catalyst::Plugin::Server::XMLRPC following the 
documentation, I get the same behaviour as Joe.

I have search the archive and found thie mail from Joe Landman , and he 
has the same problem, but unfortunately, nobody answer him.

I have copy/paste his email because his setup and mine are the same, and 
I don't have my script available right now.

To get my app running, at the end of my RPC function, I must put an 
$c->output(' ').

I would like to know if it is the correct thing to do, or I'm doing 
something wrong.

Thanks agin

Regards

Nicolas
