Great, Christian! I plan a similar application. I'm also awaiting your example! But may I ask you three short questions about your code now? a) I don't see any @DataModelSelection tag on your "currentCategory" variable, you seem to use another Bean for selection. Is there a reason you chose to not use it or just a taste question? I had some problems with DataModelSelection immediately triggering the next list of categories, but that might have been a scope issue. b) Will editing the selected item (or doing whatever with it) start a nested conversation or will some code call closeCatalog() when starting the editing process? Thanks a lot!! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978985#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
