[jboss-user] [JBoss Seam] - My Brain < Seam Conversations

Hello, I'm really trying to get my arms around how the Seam conversations work and as soon as I think I understand it, I get some behavior that doesn't match my assumptions. Currently, I am struggling with the following: - I have a page we call a "Manager Overview". This page pulls in data from various tables into little summary "portlets" (fancy divs). One of these is a list of up-coming "Reminders". - The backing bean is a Stateful Session Bean, conversation scoped. It has an @Create method with an @Begin annotation to start a long running conversation. We do this to cache the data presented on the page while its being used. - The user can click the "Add" button to add a new reminder. This link calles a ReminderBean.add action method. This method is annotated with @Begin(nested=true). - The page for adding a reminder is displayed and has Cancel and Save buttons that call ReminderBean.cancel and ReminderBean.save respectively. Both of these methods are annotated with @End - The save method, before returning a String, does this: events.raiseTransactionSuccessEvent("REMINDER_UPDATED"); - Back in the ManagerBean, we have the @Factory method for the Reminders also annotated with @Observer for the above event. - The cancel method, also annotated with @End just returns a string to redirect back to the calling page, in this case the manager overview. So, here's what I see: 1. Browse to overview (manager.seam?cid=9) 2. Click add to add a new reminder (editreminder.seam?cid=10&clr=true) 3. Fill in data and click save (manager.seam?cid=10&parentConversationId=9) 4. Newly added row appears in list and my log file indicates the observer method was called. 5. Now I click add again (editreminder.seam?cid=11&clr=true) 6. This time I click Cancel (manager.seam?cid=11&parentConversationId=9) 7. Row that was added is now gone. I suspect its something to do with transactions and/or hibernate caching or perhaps just my poor usage of conversations. Is this even the right usage for conversations? i.e. using it to cache data and updating that data using @Observer from nested conversations? Any help/insight is greatly appreciated.
