Please, help me to solve this problem:
The session.load doesn't load all shifts associated with a schedule. It does load only the first shift associated with the schedule the rest is ignored.


The schedule class has a collection of shifts ,and shift class has a collection of employees and vice versa employee class has a collection of shifts.
Any help would be appreciated, thanks

Code between sessionFactory.openSession() and session.close():
Session session = HibernateUtil.currentSession();
schedule=(Schedule) session.load(Schedule.class,id);
session.flush();


Name and version of the database you are using:
Mysql 5

Any IDEA

I'd start by checking out your equals and hashCode methods in the Shift class. Also verify that you have more than one Shift in the DB: it's pretty easy to misuse bags, accidentally having every "add" operation replace the previous contents, instead of adding to them.

I'd also check the formatting of big posts before posting (see the "Preview" button). code tags work a treat.
