Hmm, that is very similar to the GLOBALS kludge I posted, although it 
doesn't work on my machine.  Each subsequent call to setErrorArray is 
overwriting the error array.

Thus far the best I've got is:

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

   function &setErrorArray ($additionalErrorArray = NULL) {
     static $errorArray = array ();

     if ( is_array ($additionalErrorArray) ) {
       $errorArray += $additionalErrorArray;
     }

     return $errorArray;
   }
}

and for the $GLOBALS kludge:

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

   function &setErrorArray ($additionalErrorArray = NULL) {
     if ( !isset ($GLOBALS['errorArray']) ) {
       $GLOBALS['errorArray'] = array ();
     }

     if ( is_array ($additionalErrorArray) ) {
       $GLOBALS['errorArray'] += $additionalErrorArray;
     }

     return $GLOBALS['errorArray'];
   }
}

Both of those functions work 100% for anything I've thrown at them.
