Hi Yann, Thanks for your response. The problem occurs when I try to load an entity in a WebPage object. A common solution for this is to use Open Session in View filter, but it didn't work. So I found the problem. I was manually creating a spring context to inject objects in the web page. The right thing to do is to use wicket spring integration: http://cwiki.apache.org/WICKET/spring.html
