TicketObj Dependent

Hello, I’m working on a Scrip to change status and comments on creation
of dependent tickets, but apparently I can’t get DependentOn on ticket

[Mon Sep 3 18:19:30 2007] [debug]: About to think about scrips for
transaction #82336 (/opt/rt3/lib/RT/Transaction_Overlay.pm:165)
[Mon Sep 3 18:19:30 2007] [error]: Scrip 23 Commit failed:
RT::ticket::DependentOn Unimplemented in RT::Action::UserDefined. ((eval
839) line 2)

The scrip code I’m using for testing is:

my $ticket = $self->TicketObj;
my $depende = $ticket->DependentOn;
$RT::Logger->debug( “> depende: $depende <<<<<<<< \n\n” );

The ticket is created using the ‘sub-ticket’ button described in

Any information about it would be nice.
