How to store complex objects? I have an object in its list of child objects
in the child object has four list of child objects when calling
makePersistent (person) object is not saved. Help!!!!!!!!!!!!

I am call pm.makePersistent(); but  Lists

    @Persistent
        private List<ChoosedElementEntity> choosedElements = new
ArrayList<ChoosedElementEntity>();

        @Persistent
        private List<PleasantElementEntity> pleasantElements = new
ArrayList<PleasantElementEntity>();

        @Persistent
        private List<UnpleasantElementEntity> unpleasantElements = new
ArrayList<UnpleasantElementEntity>();

        @Persistent
        private List<SetViewElementEntity> setViewElements = new
ArrayList<SetViewElementEntity>();

 not saved!!!

example:


    @PersistenceCapable(table = "persons", identityType =
IdentityType.APPLICATION)
    public class PersonEntity {
        @PrimaryKey
        @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
        private Long id;

        @Persistent
        private List<OfferEntity> offers = new ArrayList<OfferEntity>();
    }

    @PersistenceCapable(table = "offers", identityType =
IdentityType.APPLICATION)
    public class OfferEntity {
        @PrimaryKey
        @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
        private Key id;


        @Persistent
        private List<ChoosedElementEntity> choosedElements = new
ArrayList<ChoosedElementEntity>();

        @Persistent
        private List<PleasantElementEntity> pleasantElements = new
ArrayList<PleasantElementEntity>();

        @Persistent
        private List<UnpleasantElementEntity> unpleasantElements = new
ArrayList<UnpleasantElementEntity>();

        @Persistent
        private List<SetViewElementEntity> setViewElements = new
ArrayList<SetViewElementEntity>();
    }


    @PersistenceCapable(table = "offer_selections", identityType =
IdentityType.APPLICATION)
    public class ChoosedElementEntity {
        @PrimaryKey
        @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
        private Key id;

        @Persistent
        private String code;

        @Persistent
        private Text cmComments;
    }

    @PersistenceCapable(table = "offer_selections", identityType =
IdentityType.APPLICATION)
    public class PleasantElementEntity {
        @PrimaryKey
        @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
        private Key id;

        @Persistent
        private String code;

        @Persistent
        private Text cmComments;
    }

    @PersistenceCapable(table = "offer_selections", identityType =
IdentityType.APPLICATION)
    public class UnpleasantElementEntity {
        @PrimaryKey
        @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
        private Key id;

        @Persistent
        private String code;

        @Persistent
        private Text cmComments;
    }
