[rt-users] Including latest transactions in RSS-Feed

[Christian Loos]

Hi,

$transactions isn't undefined but $transactions is an empty collection
and thus $transactions->Last is undefined.
This happens on tickets that don't have a Comment transaction.

Depending in the surrounding code a simple

return unless $transactions->Count;

before the 'my $comment ...' would help here.


Also instead of

my $transactions = RT::Transactions->new($session{CurrentUser});
$transactions->LimitToTicket($Ticket->id);

you maybe better write

my $transactions = $Ticket->Transactions;

as this also takes merged tickets into account.
