I;ve build a tree using richfaces and seam. The tree model is saved into a session stateful component. @Stateful @Scope(SESSION) @Name("leftTreeBean") I used Extended Persisence Context and all works but it seems that that exteded persistence context does not propagate into DAO objects (Stateless session beans). If I switch to seam managed persistence tree does not work (i supose because seam managed persistend only work inside conversation - and this cannot be the case because the tree is displayed all the time). How can I make the dao called from "leftTreeBean" use the same EntityManager? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092279#...
