[JBoss Seam] - End doesn't really end the conversation in 1.1
by andrew.rw.robinson
I have an event listener with an End attribute on it inside of a conversation scoped bean:
@Observer(UserContextUtils.APP_SET_CHANGE_EVENT_NAME)
| @End
| public void currentViewAppSetChanged(CurrentViewApplicationSetChangeEvent evt) {...}
There is no nested conversation when this method is fired. I was assuming that the long running conversation for this been would be ended and when this bean would be hit again a new instance would be created. Instead, nothing happens and my member variables are all still intact with the values from the previous conversation.
Here is the code flow:
pages.xml causes a load method to be invoked on a conversation bean marked with "@Begin(join=true)". This load method instantiates and loads data into a custom DataModel member variable.
User causes the event to fire which calls the method above with "@End". When the page is re-rendered, the data model is not null as expected and the user is displayed a old list of data.
>From my log, here is what happens during the event:
16:03:51,304 DEBUG [LiveReportBean] Received application set change event. Old: COPY, New: APSHELL
| 16:03:51,305 DEBUG [Manager] Ending long-running conversation
| 16:03:51,305 DEBUG [Manager] Storing conversation state: 95
| 16:03:51,309 DEBUG [DebugPhaseListener] The phase INVOKE_APPLICATION(5) has completed.
Here is the rendering of the next page:
16:03:51,902 DEBUG [DebugPhaseListener] The phase RESTORE_VIEW(1) is about to start.
| 16:03:51,903 DEBUG [Manager] Found conversation id in request parameter: 95
| 16:03:51,903 DEBUG [Manager] Restoring conversation with id: 95
As you can see, although conversation #95 was ended, it is still open on the next request.
I am using Seam 1.1

This is probably something obvious but i cant figure it out.
When i run the ./seam generate-entities
i get No driver found error. i was assuming it was going off the one we defined in the setup. which i verified is there
