Its times like these I want to cry....then laugh really hard, as always Gavin was right, it was in my code. The entire problem has to do in this line: | Query query = em.createQuery("from Group where group.id = :id"); | I left out the group alias, so hibernate has no idea what group.id means. It should be: | Query query = em.createQuery("from Group group where group.id = :id"); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968433#...
