Hi,
I am using Hibernate version 2.1.3 and I am having a problem when I try to add more than one object to a list and save it. There is no problem if I only add one BaseCodeListItem object to the list but when I create another object and add that to the list then do a saveOrUpdate I get a NonUniqueObjectException and I can't figure out why.
Thanks for your help.
