[otrs] Malfunction of ticket lock ?

I run into a problem today... Someone took a ticket from a queue and took control of it: Lock Ticket lock. - cfernandes (Carlos Fernandes) 08/28/2003 11:41:04 OwnerUpdate New Owner is 'cfernandes' (ID=4). - cfernandes (Carlos Fernandes) 08/28/2003 11:41:04 Another user suposelly looked to the queue and saw that ticket (I suppose it happened before the lock). And promptely went to solve it, taking its ownership: SendCustomerNotification Sent notification to '"Helpdesk" '. 08/28/2003 11:41:05 OwnerUpdate New Owner is 'jmartins' (ID=6). - jmartins (Jorge Martins) 08/28/2003 11:43:30 How the hell can this happen ? Even if the later user view hasn't refreshed (and for him the ticked is still unlocked and without owner), OTRS shouldn't allow a user to take ownership from a ticket who is already assigned... or should ? I though that when a user locks and sets the ticket ownership to him, it disappeared from the other users views.. Am I wrong with this though ? Thanks, DC
