I have a business domain class called Call and it has a List of Objects called Action.
Onnce the Action class is populated with values I set the Call object in its set method and add the Action Object into the List of Action objects in the Call class.

So to do that I use the following ql,

String hql="from Call as call left join fetch call.actions where call.callId = ?";

even after using 'left join fetch' I get NullPointerException when I try to do the following,
private List<Action> actions;
public void addAction(Action action)
{
this.actions.add(action);
}
Can any one explain why please?

Thanks and Regards,
Anish
