[Catalyst] error handling

[Angel Kolev]

sub auto : Private {
    my ($self, $c) = @_;
    if (@{$c->error}) {
        $c->stash->{error} = " Critical ERROR!! Probably missing data in 
database.";
        $c->forward('/error');
        $c->error(0);
        return 0;
    }
}

This dont work. @{$c->error} or scalar @{$c->error} always print 0 in my 
debug screen.
