Hi,

i have 2 entity bean, Rollingstock and Schedule.
Hear is some code:


  | rollingstock = new Rollingstock();
  | rollingstock.setNextRoute( "STH" );
  | rollingstock.setRoute( "HALL" );
  | schedule = new Schedule();
  | rollingstock.setSchedule( schedule );
  | 

So now i whant to persist the entitys, i thought that i just neded to do:
manager.persist(rollingstock);
then bouth rollingstock and schedule would be persist, but i get a exception when i do that.
i must do this to get both persist:

  | manager.persist(rollingstock);
  | manager.persist(schedule);
  | 

is thair any better way to persist entitys, Because in my Rollingstock entity i have a lot off relations, so when i get a Rollingstock i just whant to run persist(rollingstocko);
now i must take out evrything and do persist on each entity.

any clarification ?
