[rt-users] callback for autoclose in RT4

[inbel1]

We automatically close our tickets when replying to the requestor.
In RT3 I changed .../Ticket/Update.html
from:
if ($DefaultStatus =~ '~new$') {
         $DefaultStatus = 'open';
}
to:
if (($DefaultStatus =~ '~new$' || $DefaultStatus =~ '~open $') && Action eq 
'Respond') {
         $DefaultStatus = 'resolved ';
}

Now we have migrated to 4.0.5, but I can't find the correct callback to do this.

Anyone a clue or hint?
