Hi Andreas,

Thanks for your reply. I tried your solutions without 
success. Catalyst always try to wrap the action result 
'display' into a template. However I don't want it, I just 
want an action that throw data when called. I get an error 
from Catalyst saying it cannot find the template 'display.tt2'.
Cheers

Emmanuel
