The second key field is set here, in BizCategoriesForRecipe:
def addLink(self, catid):
print "addLink, catid = %d" % catid
if self.hasLink(catid):
raise ValueError("Category %d already linked to this recipe" %
catid)
self.new()
self.Record.catid = catid
self.save()
And this is the place where the database gets an UPDATE command, not
INSERT as it should.
All the code is here: http://dabo.codepad.org/X0tRUmVv
