Problem with asterisk 1.4 and userevent

[Francesco Romano <ml@xxxxxxxxxxx>]

I have upgraded my asterisk from 1.2 to 1.4.10.1 and the DND 
notification stopped to works. I forgott something?
This is my extensions.conf:
[app-dnd-off]
exten => *79,1,Answer
exten => *79,n,Wait(1)
exten => *79,n,Macro(user-callerid,)
exten => *79,n,dbDel(DND/${AMPUSER})
exten => *79,n,UserEvent(ASTDB|Family: DND^Value: ^)
exten => *79,n,Playback(do-not-disturb&de-activated)
exten => *79,n,Macro(hangupcall,)

[app-dnd-on]
exten => *78,1,Answer
exten => *78,n,Wait(1)
exten => *78,n,Macro(user-callerid,)
exten => *78,n,Set(DB(DND/${AMPUSER})=YES)
exten => *78,n,UserEvent(ASTDB|Family: DND^Value: On)
exten => *78,n,Playback(do-not-disturb&activated)
exten => *78,n,Macro(hangupcall,)
