It works as expected. It returns a value for the field flags (FF).
You can see this integer as a bitset, One of the bits indicates
if the field is a multiline field. I just returned from de Gentse Feesten;
(see http://www.gentsefeesten.be/english/ ), so my head is not very
clear for the moment, but if you have a look at the PDF Reference,
you will find out the correct bit position of the multiline flag.
