Transactionbatch not working as expected

Hello all, I’m having an interesting issue. When I select
TransactionBatch for the stage of my scrip, it seems to run both the
Custom action preparation code and the Custom action cleanup code
whenever I do anything - so for example, if I click ‘reply’ on the RT
interface my cleanup code gets run.

Is this what is designed to happen? When I do this with
TransactionCreate my ‘cleanup code’ will only be run when I submit
something. I’m running RT 3.6.3 on Centos5. The idea behind this scrip
is to change the owner on un-owned tickets, but not when someone
responds to a ticket and sets someone else as the owner… My scrip
looks like:

Condition:

On Correspond

Custom action preparation code:

return 0 if ($self->TicketObj->OwnerObj->Id != $RT::Nobody->id);
my @batch = @{ $self->TicketObj->TransactionBatch };
foreach my $txn ( @batch ) {
return 0 if $txn->Type ne “Correspond”;
}
return 1;

Custom action cleanup code:

my ($status, $msg) = $self->TicketObj->SetOwner(
$self->TransactionObj->Creator );
unless( $status ) {
$RT::Logger->error( “Impossible to assign the ticket: $msg” );
return undef;
}

return 1;
