This is what I wrote based on your code:

class ActionHandler {
 
  function &ActionHandler() {} // LEAVE IT EMPTY

  function &getErrorArray() {
    return ActionHandler::setErrorArray();
  }

  function &setErrorArray($additionalErrorArray = null) {
   static $errorArray = array();
   if (is_array($additionalErrorArray)) $errorArray += 
$additionalErrorArray;
   return $errorArray;
  }

}

so basically I am assuming that ActionHandler does not create a static 
instance of $this->errorArray but instead ActionHandler::setErrorArray() 
creates a static instance of a localized $errorArray which, since only 
one instance of ActionHandler exists, only one instance of the method 
exists, then only one instance of the localized variable exists and and 
that is that.  Am I off-base?
