Re: Handling Hibernate session (LazyInitializationException)
hi, you could also use an Aspekt (e.g. with Aspekj) zu reinit all lazy proxies on the next request. The Proxy objects would be detachted and serialized throw the models. With an Aspekt you can re-attach ALL hibernate proxies, without triggering the DB.

Re: Handling Hibernate session (LazyInitializationException)
Hi Anton The Problem you encounter is probably because you're holding on to a hibernate object between requests, thus the references are not valid anymore. Have a look at http://wicketinaction.com/2008/09/building-a-smart-entitymodel/ This works for us with hibernate. Matt Anton Komratov wrote: Hi, I'm using Wicket + Hibernate (without Spring).

Handling Hibernate session (LazyInitializationException)
Hi, I'm using Wicket + Hibernate (without Spring). In my application I open Hibernate *session* in WebRequestCycle.* onBeginRequest*() and close it in WebRequestCycle.*onEndRequest*(). But having association (many-to-one mappings between classes) I've got LazyInitializationException (no Session). I've just set parameter "*lazy*"=false in hibernate mapping file to "many-to-one" mappings. And it worked fine - amount of data stored in memory in this case was not critical. Since the system is growing furhter, the method with no lazy initialization is no more suitable. Could you, please, advise me a way to handle hibernate session to have lazy initialization. (Solution with no Spring is preferable). // Best regards, Anton
