	What's a good way to display an error message to the user?  I am writing a controller but if something goes wrong, I'd like to inform the user.

	I looked at the remoteprocessing module and tried:

        if ( $itemid == null )
        {
            throw new Zend_Exception ( "ERROR: missing item id, cannot continue!" );
            return;
        }

	But that didn't work...just gave me a blank page.  What am I doing wrong?
	
thanks,
Mona
