This should work if you want to register your parameters in base_class. BTW you don't need to override parameter_config at all in this case because SUPER->parameter_config returns hash reference stored in $parameter_config variable in base class. So next two lines do affect hash used by base_class. If it is not desired effect you should clone that hash: 

use Storable qw(dclone);

my $parameter_config = dclone(__PACKAGE__->SUPER::parameter_config);
$parameter_config->{max_length}{max} = 255;
$parameter_config->{max_length}{default} = 255;

sub parameter_config { $parameter_config }

Update: Fixed usage of wrong syntax (SUPER->method instead of __PACKAGE__->SUPER::method)
