No, because I always make the form from the begning...
I´m afraid because the form id don´t change much...
My original ID is:
urn:schemas-microsoft-com:office:infopath:requerimentodejustificativadefaltav00:-myXSD-2008-07-21T14-31-23
If I republish the form tu create a another form, based on the original, the ID ll be:
urn:schemas-microsoft-com:office:infopath:teste:-myXSD-2008-07-21T14-31-23
They look very similar... hehehe
