As for updating child objects, the dirty checking mechanism works just fine even if you don’t use a managed collection.

After doing so all appears to save / update fine but upon checking the child_table in the db, these changes have not been saved / updated. If I understand correctly, you're modifying a field which is part of the primary key of your entity. My advice is to follow the good practices: use a non-composite, purely technical, auto-generated primary key.

I believe this has something to do with the mappings of the map in the Parent class but can't seem to figure it out.
