Eh, I know, I tracked the changes, not sure if it'll help in my case, but it looks better, The problem is that it does not work for me, I use Toplink as JPA and when I use s:convertEntity I get: Caused by: java.lang.ClassCastException: oracle.toplink.essentials.internal.ejb.cmp3.EntityManagerImpl cannot be cast to org.hibernate.Session I understand that there should be a Seam PersistenceProvider for Toplink in order to make it work but I have no clue how to write one, Is it documented? ec:convertEntity works because I modified the code by myself.
