WeldPhaseListener fails to activate conversation context if conversation is not
found
-------------------------------------------------------------------------------------
Key: WELD-878
URL: https://issues.jboss.org/browse/WELD-878
Project: Weld
Issue Type: Bug
Components: Conversations, Web Tier integration (JSF, JSP, EL and
Servlet)
Affects Versions: 1.1.0.Final
Environment: Glassfish 3.1 B43 updated with weld-1.1.0-SNAPSHOT
(weld-osgi-bundle-1.1.0-20110329.041630-9.jar)
Reporter: Jarkko Hyöty
It seems that org.jboss.weld.jsf.WeldPhaseListener fails to activate
conversation context if a conversation is not found by the supplied
conversation id. This problem is potentially related to
[SEAMCATCH-46],[WELD-855].
JSR-299 6.7.4 Conversation context lifecycle has a requirement that 'If the
propagated conversation cannot be restored, the container _must associate the
request with a new transient conversation_ and throw an exception of type
javax.enterprise.context.NonexistentConversationException from the restore view
phase of the JSF lifecycle.'. However, the implementation of
org.jboss.weld.jsf.WeldPhaseListener.activateConversations fails to do that if
a conversation is not found by the conversation id.
{code}
private void activateConversations(FacesContext facesContext)
{
ConversationContext conversationContext =
instance().select(HttpConversationContext.class).get();
String cid = getConversationId(facesContext, conversationContext);
log.debug(RESUMING_CONVERSATION, cid);
if (cid != null && conversationContext.getConversation(cid) == null)
{
throw new
NonexistentConversationException(NO_CONVERSATION_FOUND_TO_RESTORE, cid);
}
conversationContext.activate(cid);
}
{code}
Recovering from the exception becomes difficult since the context is not
active. Typical symptom is 'java.lang.IllegalStateException: Unable to load
current conversations from the associated request, something went badly wrong
when associate() was called
at
org.jboss.weld.context.AbstractConversationContext.getCurrentConversation(AbstractConversationContext.java:413)'
