Criteria query return repeated objects when quering for an object with Lazy one to many association --------------------------------------------------------------------------------------------------- Key: HHH-2179 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2179 Project: Hibernate3 Type: Bug

Components: query-criteria Versions: 3.2.0.cr2 Environment: Windows, HSQLDB, Hibernate Annotations Reporter: Lucas Machado Attachments: testVersao.rar In the above scenario: ClassA (1) -- (*) ClassB to implement this we we have the following annotation in ClassA. @OneToMany( cascade = CascadeType.ALL, fetch=FetchType.EAGER) public Set<ClassB> getBs(){ .... } in the database we have 1 row representing ClassA and 3 rows representing ClassB (associated with the unique ClassA) The problem is: If we query for "from ClassA" returns 1 instance of ClassA as expected if we repeat the query using Criteria Criteria crit = session.createCriteria(ClassA.class); List<ClassA> l = crit.list(); The result is a list with 3 positions filled by the same instance of ClassA. If we change the FetchType to Lazy the problem is solved Attached is a sample maven-eclipse project with a test case
