Hibernate version: 3.1
What if there is a List of components (with composite-element) with multiple objects, but every object in the list has all its fields with null. An object with all fields null is stored as simply null (as per the documents). But in org.hibernate.collection.PersistentList.needsInserting() says to always insert if the entry is null... and then Hibernate tries to repeat insers it has already done, giving db constraint violations.
Well... that's my interpretation.
Here's the stack trace:
