Invite to control channel doesn't work

[rhuelga]

We have created a control channel (&cchan) and associated it to a group. When we try to invite a facebook contact to the channel using:

/join &cchan
channel &cchan set fill_by group  
channel &cchan set group cgroup  

and in &bitlbee channel do: /invite ContactName &cchan

in the channel we get:

*** Inviting ContactName to channel &cchan

but it is not added to the channel, as show by blist.

If we do this with a gtalk contact everything works and we get:

*** ContactName (xxxxxxxxxxxxxxxxxxxxxx@public.talk.google.com) has joined
    channel &cchan
*** localhost has changed mode for &cchan to +v ContactName

Not really sure how this would work when there's no server-side concept of groups
