[jboss-user] [JBoss Seam] - conversations join/nest

Hi, In my application (Seam 1.2.1GA) I use 2 level of nested conversations to navigate across categories, subcategories and items of each subcategory. That's my scenario: Bean 1 (select a category) -> Root Conversation Bean 2 (select a subcategory) -> Nested inside the root Bean 3 (edit an item of the subcategory) -> Nested inside the previous When I switch between categories the subcategories are updated, when I click on a subcategory I see the respective items, and when I click on an item I can edit its properties. In order not to create a new (or new nested) conversation each time I switch cat, subcat or item I have written this method (called in the @Factory methods of my backing beans) to always join the correct level of conversation. | public void joinSameOrNest(Class caller) { | Conversation current = Conversation.instance(); | boolean started = false; | for (ConversationEntry entry : ConversationEntries.instance().getConversationEntries()) { | if(entry.getDescription().equals(caller.getName())) { | entry.select(); | log.info("Joining conversation " + caller.getName()); | current.begin(true, false); | started = true; | } | } | if(!started) { | log.info("Starting nested conversation " + caller.getName()); | current.beginNested(); | } | } | I recognize the level of conversation since, in the @Factory methods of my backing beans I first call the method: | public void setDescription(Class caller) { | Conversation.instance().setDescription(caller.getName()); | } | Until the first level of nesting it works fine and in the conversation stack I always see the root and the nested, but when I try to edit an item (starting the 2nd level of nesting) I get an exception: java.lang.IllegalStateException: beginNested() called with no long-running conversation Is it actually possible to have multiple nesting? Is something wrong in my method? I was using the annotations before @Begin(nested/join), but a limited behaviour can be achieved with that. Or am I wrong? Thanks for any suggestions!
