From Joomla! Documentation

public function bind($array, $ignore = '')
{
  if (isset($array['metadata']) && is_array($array['metadata']))
  {
    $registry = new JRegistry;
    $registry->loadArray($array['metadata']);
    $array['metadata'] = (string) $registry;
  }
  return parent::bind($array, $ignore);
}
