I have this in one of my object classes.

static $errorTracker = NULL;
public function __construct(){
$this->errorTracker = ErrorTracker::getInstance();
}

protected function _isError($error){
return $this->errorTracker->_isError($error);
}



And in the ErrorTracker class,

public static function getInstance (){
static $instance;
if (!isset($instance)){
$c = __CLASS__;
$instance = new $c;
}
return $instance;
}


When this is run, I get:

Fatal error: Call to a member function _isError() on a non-object

Any idea why the ErrorTracker is falling out of scope? Thanks.
