echo?

Hello everyone,

I've been stuck in a previous projects that use the older versions, but 
now I'm using 0.9.2 and can't seem to echo from my controllers::actions().
I tested this theory by using a header location to http://google.com 
instead of an echo 'I come here'; and it worked. Is the ZFW using some 
kind of output buffer?
It also only seem to have this behavior when I'm using 
:module:controller:action?
Kind regards,
Peter Pistorius
