in thread Problem generating builder functions with Moose for inherited objects

That seems to work, thanks! :) That puts the BUILD method in the Parent class at this:
sub BUILD { my $self = shift; my $meta = $self->meta; print("BUILD called for " . __PACKAGE__ . "\n"); no strict; foreach my $build_attribute ($meta->get_all_attributes) { my $build_attname = $build_attribute->name; print("Creating builder for attribute [" . $build_attname . "] +\n"); if (!defined *{__PACKAGE__ . '::_build_' . $build_attname}) { *{__PACKAGE__ . '::_build_' . $build_attname} = sub { my $self = shift; my $meta = $self->meta; my $attribute = $meta->find_attribute_by_name($build_a +ttname); if (!defined $attribute) { Carp::confess("Error: Can't + find attribute [$build_attname]\n"); } my $type_name = $attribute->type_constraint->name; #if ($attribute->type_constraint->is_a_type_of("ArrayR +ef[Any]")) { return []; } if ($type_name =~ /^ArrayRef/) { return []; } #elsif ($attribute->type_constraint->is_a_type_of("Has +hRef[Any]")) { return {}; } elsif ($type_name =~ /^HashRef/) { return []; } elsif ($attribute->type_constraint->equals("Str")) { r +eturn ""; } elsif ($attribute->type_constraint->is_a_type_of("Num" +)) { return 0; } else { return undef }; }; } } use strict; }
Unfortunately, the 2 commented lines didn't work out, so I had to replace them with a ->name regex match.

    You have the Moose::Meta::Attribute object already in $build_attribute in the outer loop, so you can do your test simply on that one:
    $result = $build_attribute->type_constraint->is_a_type_of('ArrayRef') +? 'it's an ArrayRef' :'not an ArrayRef';
    I just tried this in one of my Moose classes and it works for me that way.
