Hi, I am getting the following exception when trying to get the size of a one to many relation in a PostLoad method. Of course, this code runs inside a SLSB DAO and should so be inside a transaction: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358) | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350) | at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:97) | at org.hibernate.collection.PersistentSet.size(PersistentSet.java:139) | at com.servengine.contentmanager.CMCategory.postLoad(CMCategory.java:52) I am using Set as the type for the relation and have set Eager load. How am i suppoused to access EJB CMRs from callback methods lik PostLoad? Thanks for any help, Ignacio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054980#...
