Loading a list from a database using eclipselink jpa

I have three tables in a derby database. Schedule, EmployeeSchedule, EmployeeScheduleInfo. The schedule has an EmployeeSchedule list, and EmployeeSchedule has an EmployeeScheduleInfo list.

I am using eclipselink jpa and I created my objects and controllers from netbeans. My problem is that when I load the Schedule object from the database, the list of EmployeeScheduleInfo objects in all EmployeeSchedule objects does not load, when I debug it, I see

{IndirectList: not instantiated}
