Can you paste in some code? A class or two and the JSP that demonstrates the problem would be very helpful. The only time I've had problems with lazy loading was when I was trying to use entities that I had stored in the HttpSession on previous requests.

Here is what I to in a Filter before chaining the request to Stripersist: User user= (User)httpSession.getAttribute("user"); if(user==null){ user.setUserNbConnect(user.getUserNbConnect()+1); Stripersist.getEntityManager().persist(user); httpSession.setAttribute("user", user); Stripersist.getEntityManager().getTransaction().commit(); } In the ActionBean: order = new Order(); order.setUser((User)httpSession.getAttribute("user")); In the JSP: <s:select name="order.user"> Here is the class seen by Entityformatter: class com.package.User_$$_javassist_9 (or cglib) > The only time I've had problems with lazy loading was when I was > trying > to use entities that I had stored in the HttpSession on previous > requests. this is the case. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Stripes-users mailing list Stripes-users@... https://lists.sourceforge.net/lists/listinfo/stripes-users

	Re: Stripersist and dropdown menu / lazy loading by Aaron Porter-3 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Sounds like I need to dust of the old deproxify code that Remi wrote for Stripernate and stick it into Stripersist. OK. I've updated SVN. Give that a shot and let me know if it works. Aaron Lionel wrote: Aaron Porter wrote: Hi Lionel, We'll probably need more than that to go on. Can you paste in some code?

	Re: Stripersist and dropdown menu / lazy loading by Aaron Porter-3 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message The problem with sticking entities in the HttpSession is they get detached when the request ends. If you're trying to do lazy loading after they're detached it won't work. What I do now is stick the id in the session instead of the entity then I have a getUser() either in a base ActionBean or ActionBeanContext that loads the entity if not cached, caches it, and gives it back. The other option is to force the lazy loading properties to load before the entity gets detached but that gets to be a maintenance nightmare.

Learn more about Nabble's security policy. I tried, but it didn't change. DEBUG EntityUtil:194 - Finding..... @Id for com.package.User$$EnhancerByCGLIB$$d8977ea6 DEBUG EntityUtil:194 - Looking for @Id on field userLogin DEBUG EntityUtil:194 - Found @Id for com.package.User on field userLogin But the id value is still null. If I log user.getUserLogin() in the actionBean, I can see it's value. If I use a session.get(login) instead of a session.load(login) everything works fine so I will use that for now. By the way, your deproxyfication only works for cglib. With javassist (the new default with hibernate 3.3) the classname is not the same: com.package.User_$$_javassist_9 There an underscore that needs to be removed: Unable to deproxify CGLIB proxy: com.package.User_ not found !

Learn more about Nabble's security policy. Just a little issue with the last release: Stripersist now searches for persistance units in every loaded jar it finds. I have an activemq-all.jar in my tomcat/lib, and it crashes: No Persistence provider for EntityManager named activemq. Not a big deal, but on the production envrionment, it's not very nice to have such an exception when the server starts. Is there some way to avoid that ?
