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?
