Hello, im using Hubernate 3.1.3 with Annotations 3.1b9. When i use an eager fetch strategy, and i execute a findall method (using criteria without any criteria), in list of results, the same object appears twice, while if i use a lazy fetch strategy only one time appears. Of course in database only one object is found, for example if findAllCars with lazy strategy returns Car A and Car B, in Eager returns Car A, Car A, Car B and Car B.

This is used in a One to Many, Many to One with middle table with relationship attributes.

Anybody knows why happens?

Thank you very much.

just don't know if it is a bug or what, but if i use a createQuery rather than criteria works perfectly.

This is common behaviour.
Search forum and JIRA for explanation.

please read the collection chapter included in Hibernate Annotations reference documentation. Esp the difference between a bag semantic and other collection semantics
