I have to create a application that manages about 1 milion entries. The entries are organised hierarchical in a tree. Tree is made in such a way that not very many entries are displayed at a time. The tree is displayed in the left side of all application pages (with some exception). I have a dilemma here: should I store the tree state in conversation context ? or in session context? I know the advice is to not store much info in session context but on the other side, my tree has to be displayed nearly all the time. Is there a seam example with a tree in the left side somewhere? If the entities are stored in the session how do I solve "LazyInitializationException" ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088375#...
