Hard to guess how an empty uuid is represented, 4D made a strange soup with it. For my own, I prefer set empty uuid to "0"*32 myself, given that a/ uuid is a number, represented as an alphanumeric string (hexadecimal) but it remains a number b/ empty numbers in 4D have always been represented by 0 -- Arnaud de Montard ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
