[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-288) Execute the EJB 3.0 callback on collection change

[ http://opensource.atlassian.com/projects/hibernate/browse/EJB-288?page=co... ] Hardy Ferentschik commented on EJB-288: --------------------------------------- Added the collection post update event listeners. There is a remaining questions though regarding 'de-duplication' of events. For example, a Cat has a collection of Kittens: class Cat { ... @OneToMany(cascade = CascadeType.ALL) public List<Kitten> getKittens() { return kittens; } @PostUpdate private void someLateUpdateWorking() { ... } ... If we now load a persisted Cat instance with a set of Kittens and replace the kittens: cat.setKittens(new ArrayList<Kitten>()); the post update handler will be called twice since Hibernate core will fire a PostCollectionRemoveEvent and PostCollectionRecreateEvent. In entity manager there is no way currently to 'de-duplicate' these two events. Does this violate the JPA spec? Is there a way in core to only trigger one event? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
