Is it possible to have one method start a transaction and another method finish it?

In the following I want add() to start the transaction and save to commit it, but the flushmode is not getting set at all and the record gets persisted at the end of add():

@Name("personPage")
@Scope(ScopeType.CONVERSATION)
@Transactional
public class PersonPage implements Serializable {

     @Begin(join=true, flushMode=FlushModeType.MANUAL)
     public void add() {          
          personHome.persist();
     }

     @End
     public void save() {
          personHome.getEntityManager().flush();
     }
}
