OnetoMany - cascade all

[trouby]

Hey,

I think I have a very basic confusion regarding cascade,
I have the following simple relationship:

public class message {

private Set<Comment> comments;

@OneToMany(mappedBy = "message", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
public Set<MessageComment> getComments() {
 return comments;
}

//set...
}

And

private Message message;

@ManyToOne(optional=false)
public Message getMessage() {
return message;
}

//setter

I'm trying to persist a new comment by:

//assuming a message with id 1 exists in db
Message m = entityManager.find(Message.class,new Long(1));
Comment c = new Comment();
c.setMessage(m);
m.getComments.add(c);
entityManager.merge(m);

I don't want to persist the comment directly but through the message,

if 'getComments' is cascaded with ALL, shouldn't the new comments get persisted when em.merge(m) is invoked?




Thanks,

Asaf.
