That above code failed for me.  Say for instance you're in FileHandler 
class method getBackupFile():

if (!$fileID) ActionHandler::setErrorArray(array('action' => 'Backup 
file not found'));

Ok, right after this line, in the *very same method*, I do this for fun:

print_r(ActionHandler::getErrorArray());

I see

Array (action => Backup file not found)

OK?

Now I am out of the method and back in ActionPerformer::perform() method:

$fileGen =& new FileGenerator($db, $table);
$fileBackupContents = $fileGen->getBackupFile(); // THIS IS WHERE I SEE 
MY FIRST print_r() statement

..and have returned to my ActionPerformer::perform() method, the VERY 
NEXT LINE I do this:

print_r(ActionHandler::getErrorArray());

I see

Array ()

This happens if even I implement YOUR code into the mix.  Instead, were 
I to use $GLOBALS, everything works.  It's the PHP4 version of a 
"singleton" class w/o the singleton structure that I truly believe fails 
in PHP 4 at least 4.3.2 that I'm using at work.
