I've been fighting this one for a few days and I'm completely at a loss. I've read the docs, examples, forums, etc.
I have a parent object with a map of Integer->Integer. The parent is saved initially and then the map is created. The parent is updated. Hibernate sees my collection and DELETES IT! I've tried everything, saving the parent/map together (no update, just 1 save), using saveOrUpdate() (with an interceptor for null-value), cascade=all, cascade=save-update, lazy=true, etc. etc. Nothing seems to work. Any help would be appreciated. I'm really at a loss on this. I have another class that uses a set and that works just fine.
Prereqs:
Hibernate 2.1
Database Oracle 10
I'm using Spring as well!
