Hi,

I am trying to use the XML-BMEcat Module and I presume that there is a problem with something outdated but I am absolutely stuck. There are some subroutines with similar problems, e.g.:

sub creatCatalogGroup {
   my ($self, $key) = @_;

# pls.don't forget this problem
  (exists $self->{$key}) ? return $self->{$key} :
        return Push2PsH($self, $key, CatalogGroup->new());
}

[download]

Calling it with:

my $CatalogGroup = $GroupSystem->creatCatalogGroup('02');

[download]

Throws an error and the script stops:

Not a HASH reference at /cpan/XML/BMEcat.pm line 637.

which is (exists $self->{$key}) ? return $self->{$key} :

Data::Dumper gives me 
$VAR1 = bless( 
{}
, 'GroupSystem' );
$VAR2 = '02';
for @_

Now I cannot stop thinking that it must be about exists defined but that seems not logical to me. I tried it on perl 5.10.1 and 5.20.2 which are the versions I have available on webservers.

As far as I read everywhere exists is not deprecated but defined is that makes me think I am on the wrong track thinking about this part of the subroutine.

I would appreciate any hint into the right direction.

Cheers Niko
