I am trying to save only 1 person and my intent is to replace owner of addresses (not to share them between these 2 persons).
Is there any option that I can set (in mapping or otherwise) so constraints like these are silently ignored?
Because doing account1.getPerson().setAddresses(null); before I am setting same addresses to another person is pretty much redundant in this case??
