[jboss-user] [JBoss Seam] - Exception: No session or session closed

I'm using JBoss 4.2.1.GA and Seam 2.0 CR1. I have an SFSB as follows | */ | @Stateful | @Name(value = "fairListing") | @Scope(ScopeType.SESSION) | public class FairListBean implements FairListLocal { | | @In | EntityManager entityManager; | | @In | FacesMessages facesMessages; | | @DataModel | private List<FairDTO> fairs; | | @DataModelSelection("fairs") | private FairDTO fair; | | @Factory("fairs") | public void list(){ | fairs = new FairQM(entityManager).findAll(); | } | | public void showDetails(){ | this.fair = entityManager.merge(fair); | } | } | I'm using this to manage a Master-Detail page showing a dataTable of fairs. when a fair is selected, the showDetails() action is called and the details of a fair are shown below the dataTable using an <a:outputPanel>. I read that using the ManagedPersistenceContext configured in components.xml and injected in your code does not throw LazyInitializationException (hope i got that right :-) ). I was quite surprised to find this exception being thrown. Can anyone point out what i'm doing wrong? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4089236#...
