Re: T5 contributeMasterDispatcher - how to have
default rootContext access be part of it
I've already sent a direct e-mail out to Stephane Decleire with the info
of this small error. I'll keep an eye out for the change on the wiki and
if it doesn't get thru, do the extra effort of signing-up and trying to
make the change myself ;-)
Anyways - another great example of the building T5 community.
Keep it up guys,
-J.
