* @param mixed $conditions 
* @param string $sort 
* @ param mixed $fields 
* @param mixed $queryLinks 
* 
* @return array 
*/ 
function & find ($conditions, $sort = null, $fields = '*', $queryLinks = true) 
{ 
$rowset =& $this->findAll($conditions, $sort, 1, $fields, $queryLinks); 
if (is_array($rowset)) { 
$row = reset($rowset); 
} else { 
$row = false;
