Conversation.isLongRunning() causes NPE
---------------------------------------

                 Key: JBSEAM-3566
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3566
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.3.CR1
         Environment: JBoss 4.2.2, Seam 2.0.3.CR1
            Reporter: Nikolay Elenkov


I have a couple of methods that log conversation start/end for debugging purposes in may app. 
The code is pretty simple:

@Observer(value = "org.jboss.seam.beginConversation")
public void onConversationStart() {
  log.debug("CONVERSATION Started");
  Conversation c = Conversation.instance();
  log.debug(String.format("id: %s; isLongRunning %s; viewId: %s", 
	c.getId(), c.isLongRunning(), c.getViewId()));
}

Most of the time that works OK, but I get an occasional NPE, seems to happen when 
you access the app right after JBoss has started. Here is the trace:

Caused by: java.lang.NullPointerException
	at org.jboss.seam.core.Manager.isReallyLongRunningConversation(Manager.java:230)
	at org.jboss.seam.core.Conversation.isLongRunning(Conversation.java:308)
	at myapp.LoggerBean.onConversationEnd(LoggerBean.java:145)
