So after an embarrassing amount of time debugging, I've finally stripped this issue ([http://stackoverflow.com/questions/4621589/perl-moose-typedecorator-error-how-do-i-debug][1]) down to a simple test case. I would humbly request some help understanding why it's failing :) Here is the error message I'm getting:
plxc16479 $h2/tmp/tmp18.pl
This method [new] requires a single argument. at /nfs/pdx/disks/nehalem.pde.077/perl/5.12.2/lib64/site_perl/MooseX/Types/TypeDecorator.pm line 91

Wrapper test script:
use strict;
use warnings;
BEGIN {push(@INC, split(':', $ENV{PERL_TEST_LIBS}))};
use Program::Plist::Pl;
my $obj = Program::Plist::Pl->new();
Program::Plist::Pl file:
package Program::Plist::Pl;
use Moose;
use namespace::autoclean;
use Program::Types qw(Pattern); # <-- Removing this fixes error
use Program::Plist::Pl::Pattern;
sub BUILD {
my $pattern_obj = Program::Plist::Pl::Pattern->new();
}
__PACKAGE__->meta->make_immutable;
1;
Program::Types file:
package Program::Types;
use MooseX::Types -declare => [qw(Pattern)];
class_type Pattern, {class => 'Program::Plist::Pl::Pattern'};
1;
And the Program::Plist::Pl::Pattern file:
package Program::Plist::Pl::Pattern;
use Moose;
use namespace::autoclean;
__PACKAGE__->meta->make_immutable;
1;
Notes: While I don't need the Pattern type from Program::Types in the above code, I do in other code that is stripped out. The PERL_TEST_LIBS env var I'm pulling INC paths from only contains paths to the project modules. There are no other modules loaded from these paths.
It appears the MooseX::Types definition for Pattern is causing problems, but I'm not sure why. Documentation shows the syntax I am using, but it's possible I'm misusing class_type as there isn't much said about it. Intent is to be able to use Pattern for type checking via MooseX::Params::Validate to verify the argument is a 'Program::Plist::Pl::Program' object.
I've found that removing the intervening class Program::Plist::Pl from the equation by directly calling Pattern-new from the tmp18.pl wrapper results in no error, even when the Program::Types Pattern type is imported.
