> 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
