Hi all, Perldoc of Kernel/System/MasterSlave.pm states: Kernel::System::MasterSlave - to handle all ticket master slave tasks ... SYNOPSIS All functions to handle ticket master slave tasks ... PUBLIC INTERFACE new() create an object use Kernel::System::LinkObject; my $LinkObject = Kernel::System::LinkObject->new( ConfigObject => $ConfigObject, LogObject => $LogObject, DBObject => $DBObject, TimeObject => $TimeObject, MainObject => $MainObject, EncodeObject => $EncodeObject, ); Is it a typo or do I really need to create a LinkObject in order to use MasterSlave functionality? Should I do $LinkObject->MasterSlave() or MasterSlaveObject->MasterSlave()?
