[dev] conf.php not getting loaded

[Nathan Mills]

I found myself needing to call a function from an application in 
prefs.php to populate an enum field. I ran across the issue with 
including base.php in prefs.php, did some research, and found that I 
should be including the one file with the function I need.

That part works, but for some reason conf.php is getting lost when (and 
only when) I call the function. If it's never called from prefs.php, 
there's no problem. What am I doing wrong?

I'm doing this in prefs.php:

require_once dirname(__FILE__) . '/../lib/Astdial.php';

$_prefs['channel'] = array(
     'value' => '',
     'locked' => false,
     'shared' => false,
     'type' => 'enum',
     'enum' => Astdial::listDestinations(),
     'desc' => _("Phone number where you can be reached")
);

This is the function in question:

function listDestinations()
{
     static $dests;
     if(is_null($dests)) {
         $apiargs = array(
             'addresses' => array(''),
             'addressbooks' => array('asterisk'),
             'fields' => array()
         );
         $result = $GLOBALS['registry']->call('contacts/search', $apiargs);
         if(is_a($result, 'PEAR_Error')) {
             return $result;
         }
         $dests = array();
         if(!empty($result)) {
             $result = $result[''];
             foreach ($result as $dest) {
                 $dests[$dest['id']] = $dest['name'];
             }
         }
         uasort($dests, 'strcoll');
     }
     return $dests;
}

Thanks,
