I am using Jboss 4.2 with seam. I have a problem. I need to convert entity that has been lazy fetched to it's original class, so I can persist it. Trying to persist entity that is lazy fetched (enhanced by javassist) would cause exception. I have this problem because I can not declare persist cascade between main entity and sub entities which are lazily fetched. ( project tracks historical data, and unfortunately database does not have triggers ) I have managed to solve problem by using hibernate session | ((Session)manager.getDelegate()).evict(main.getSubEntity()); | SubEntity sub= manager.find(SubEntity.class,main.getSubEntity().getId()); | | osoba.setSubEntity(sub); | But this kind of solution is not acceptable because then I am tide to jboss and hibernate, ( It is imperative that I have ability to move code to another application server) Please help. Thanks in advance Kruno. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4097744#...
