How change CC field upon ticket creation?

[Aikido Guy]

I'm using Trac 1.4.2 and am trying to create  a little plugin that will set the CC to a value when the ticket is created (in order to send out ticket creation email notifications). I then remove the CC afterwards in order to stop the email notifications.

1. I am able to change the description field but not the CC field

2. Is there a better way than to use ITicketManipulator?

3. Should I be using "cc" rather than "CC" as per CarbonCopySubscriber event.target['cc']? I tried both ways and, if I recall correctly, both did not work

4. Should I be calling something like _ticket_change_subscribers to indicate the change I've made to the ticket's cc field? I was under the impression that everything would happen magically under the hood :)

trac.ini:

   [notification-subscriber]

   always_notify_cc = CarbonCopySubscriber 

   [[ticket]]

   default_cc = 

And my custom plugin looks like the following (extra stuff removed):

implements(ITicketManipulator)

def validat_ticket(self, req, ticket):
   if '/newticket' not in str(req):   # is there a "better" way to check this?
           ticket["CC"] = ""    # remove the CC if we are not creating a new ticket
           return []

    if ticket["status"] == "new":
          if ticket["CC"]==None or ticket["CC"]=="":
              ticket["description"] = "blah" # this works
              ticket["CC"] = "blah" # but this does NOT work

   return []

Any tips would be gratefully accepted!

Kindly,
