Force default won't save "true" value

I'm using viewfield.module v 1.3.2.9 2007/07/10 23:07:25, pulled down from cvs. I know it's not 100% stable, but it works really well - this is an awesome tool when combined with node reference!

However, I can't seem to get the force default checkbox to save a "true" or "checked" value and I'd love to get viewfield off my edit form. Any thoughts? I just upgraded from v 1.2, not sure and ran the upgrade script. Below is an export of my field - as you can see, it won't save a value for force default:

$content[fields]  = array (
  0 => 
  array (
    'widget_type' => 'viewfield_select',
    'label' => 'Projects Detail',
    'weight' => '0',
    'force_default' => '',
    'description' => '',
    'group' => false,
    'required' => '1',
    'multiple' => '0',
    'allowed_views' => 
    array (
      'projects_of_specific_nepa' => true,
      0 => 1,
      'listing_activities' => false,
      'listing_contractors' => false,
      'listing_nepas' => false,
      'listing_projects' => false,
      'listing_surveys' => false,
      'comments_recent' => false,
      'frontpage' => false,
      'popular_alltime' => false,
      'popular_recent' => false,
      'tracker' => false,
    ),
    'super_default' => 0,
    'super_default_widget' => 
    array (
      0 => 
      array (
        'field_projects_detail' => 
        array (
          'vnames' => 'projects_of_specific_nepa',
          'vargs' => '[nid]',
          'override_default' => true,
        ),
      ),
    ),
    'field_name' => 'field_projects_detail',
    'field_type' => 'viewfield',
    'module' => 'viewfield',
  ),
);
