Just read the specs for JPA2.1 and found one thing that I really miss in JPA absent: events in which changes to the BM are formally allowed. In the last few years I've posted and have seen many posts here on the fact that the before persist, before merge, etc events are only partial usable. The main issue is that if you modify entities in these events the changes may or may not be included in the database. In order to write good encapsulated business models these types of events are a necessity. At the moment I have pieces of such code in my UI (and have to repeat it in my web UI and SOAP interface).
Do you know if I can just bring this concern to Linda DeMichiel's attention by emailing her? Or is there a more formal way to address the JPA 2.1 committee?
