[jboss-jira] [JBoss JIRA] (WFLY-13662) Weld Conversation Context Logs when not using Conversation Context

[Matěj Novotný (Jira)]

    [ https://issues.redhat.com/browse/WFLY-13662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14228673#comment-14228673 ] 

Matěj Novotný commented on WFLY-13662:
--------------------------------------

bq. when any page with a view scoped bean is loaded it appears to trigger an @Initialized event for ConversationScoped...

This is strange. {{@ConversationScoped}} and {{@ViewScoped}} are two different things. I don't see how using one triggers another.
Though I don't really know how JSF implements views scoped (that scope is *not* part of built-in CDI scopes, therefore CDI doesn't control it). It could be that they are using conversations to handle view scoped lifecycle, although it sounds a bit crazy.

bq. I'm guessing this is just how the Lazy Initialization works

No, that shouldn't be the case. Lazy init is all about not actually creating or restoring the context until you first attempt to access conversation context bean.

bq. Unfortunately it's just log messages that are printed and not stack traces and it is pretty rare at this point I'm guessing one out of 10000 requests

Ah, ok. So its intermittent. From issue description I originally thought you can reproduce that every time.
