[jboss-jira] [JBoss JIRA] (WFLY-2387) CDI injection in entity listeners failing

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-2387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13164305#comment-13164305 ] 

Scott Marlow commented on WFLY-2387:
------------------------------------

{quote}
When invoked from within a Java EE environment, the callback listeners for an entity share the enter-
prise naming context of the invoking component, and the entity callback methods are invoked in the
transaction and security contexts of the calling component at the time at which the callback method is
invoked. [45]
[45] For example, if a transaction commit occurs as a result of the normal termination of a session bean business method with transac-
tion attribute RequiresNew, the PostPersist and PostRemove callbacks are executed in the naming context, the transac-
tion context, and the security context of that component.

John, I'm also not exactly sure how the entity listener scope impacts this jira exactly.
