[SOLVED] How do you get checkboxes to be checked in ValidForm Builder?

I need to get each of the checkboxes to be pre-selected in ValidForm Builder based on their default values if they have were selected when the record initially got written to the DB Table.

Here is my code:

  $objType = $objGroup->addField('locationType', 'Location Type', VFORM_CHECK_LIST,
    array('required' => true),
    array('required' => 'Location Type is required'),
    array(
      'fieldclass' => 'vf__inlineButtons',
      'tip' => (($_SESSION['auth']['tips'] && $_POST['action'] != 'delete') ? VFB_TIP_LOCATIONS_LOCATIONTYPE : NULL),
      (($_POST['action'] == 'delete') ? 'fieldDisabled' : 'fieldEnabled') => (($_POST['action'] == 'delete') ? 'disabled' : 'enabled'),
      'default' => $default['locationType']
    )
  );
  $objType->addField('Destination', 'D');
  $objType->addField('Sales', 'S');
  $objType->addField('Pickup/Dropoff', 'P');
  $objType->addField('Both, Sales & Pickup/Dropoff', 'B');

Here's my trial & error attempts to get it to work:

(1) I removed the 'default' => $default['locationType'] and added 'checked' to each $objType->addField(). So In the code above, that is all 4 of the $objType->addField()'s have the 'checked' element added to them. Result is only the last checkbox gets checked -- no success.

(2) I removed the 'default' => $default['locationType'] and added 'selected' to each $objType->addField(). So In the code above, that is all 4 of the $objType->addField()'s have the 'selected' element added to them. Result is only the last checkbox gets checked -- no success.

(3) I removed the 'default' => $default['locationType'] and added 'checked' => 'checked' to each $objType->addField(). So In the code above, that is all 4 of the $objType->addField()'s have the 'checked' => 'checked' element added to them. Result is the script generates nothing -- no success.

(4) I tried this too -- 'default' => array("D", "", "P", "") -- no success.

(5) I tried this -- 'default' => array(true, false, true, false) -- all boxes get checked -- no success.

(6) I tried this -- 'default' => array("1", "0", "1", "0") -- only the first box gets checked -- no success.

(7) I tried this -- 'default' => array(1, 0, 1, 0) -- only the first box gets checked -- no success.

I am thinking that ValidForm Builder is not ready for checkboxes.

Here is the relevant VFB code (if it helps you see where the issue is). NOTE on 2/22/2014 through my extended T&E troubleshooting I do not believe this class file is even loaded or used in the production of the HTML. Continuing to dig...:

        if (!$blnSimpleLayout) {
            //*** We asume that all dynamic fields greater than 0 are never required.
            if ($this->__validator->getRequired()) {
