[Catalyst] Problem with prefetch DBIX::Class

[Marc Perez]

Hi,
My name is Marc, I'm not use to write to the list but I have a problem
which I dont know exactly how to solve.
I have this two models:

FIRST:
package cmsDB::Files;
use strict;
use warnings;
use base 'DBIx::Class';
__PACKAGE__->load_components("Core");
__PACKAGE__->table("files");
__PACKAGE__->add_columns(
  "file_id",
  { data_type => "INT", default_value => undef, is_nullable => 0, size => 10 },
......
__PACKAGE__->has_many(
  "fieldfiles",
  "cmsDB::Fieldfiles",
  { "foreign.file_id" => "self.file_id" },
);

SECOND:
package cmsDB::Fieldfiles;
use strict;
use warnings;
use base 'DBIx::Class';
__PACKAGE__->load_components("Core");
__PACKAGE__->table("fieldfiles");
__PACKAGE__->add_columns(
  "file_id",
  { data_type => "INT", default_value => undef, is_nullable => 0, size => 10 },
  "language_id",
  { data_type => "INT", default_value => undef, is_nullable => 0, size => 10 },
  "name",
  {
    data_type => "VARBINARY",
    default_value => undef,
    is_nullable => 1,
    size => 250,
  },
........
__PACKAGE__->set_primary_key("file_id", "language_id");
__PACKAGE__->belongs_to("file_id", "cmsDB::Files", { file_id => "file_id" });
__PACKAGE__->belongs_to(
  "language_id",
  "cmsDB::Languages",
  { language_id => "language_id" },
);


I'm doing the next query:
my $files = $catVar->model('cmsDB::Files')->search(
			{
				'me.cmsobj_id' => $this->cmsobj_id,
				-or => [mime_type => 'image/jpeg',mime_type =>
'image/gif',mime_type => 'image/png'],
				'fieldfiles.language_id' => $langId
			},
			{
                join => 'fieldfiles',
                prefetch => 'fieldfiles'
			}
		);

When I try to access the fieldfiles data:

while( my $file = $files->next() ) {
print($file->fieldfiles->name)
}

I get the error:
Can't locate object method "name" via package "DBIx::Class::ResultSet"

If I dump $file->fieldfiles:

$Data::Dumper::Indent = 3;
$Data::Dumper::Maxdepth = 3;
Dumper($file->fieldfiles->name)

I get this:

$VAR1 = bless( { '_source_handle' => bless( { 'source_moniker' =>
'Fieldfiles', 'schema' => bless( { 'class_mappings' =>
'HASH(0xa521c78)', 'source_registrations' => 'HASH(0xa5220c8)',
'storage' => 'DBIx::Class::Storage::DBI::mysql=HASH(0xa52e4b8)' },
'cmsDB' ) }, 'DBIx::Class::ResultSourceHandle' ), '_in_storage' => 1,
'_column_data' => { 'link' => '', 'language_id' => '1', 'name' =>
'Jamón y Queso - Botiga', 'file_id' => '5', 'description' => '' } },
'cms::Model::cmsDB::Fieldfiles' );


Maybe Im doing something wrong...
I would really appreciate any help.

Thanks

Marc Pérez
