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

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-2387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12924666#comment-12924666 ] 

Stuart Douglas commented on WFLY-2387:
--------------------------------------

It has nothing to do with registration, it has to do with instantiation. 

Basically just don't create the entity listener until it is needed (i.e. some entities exist) and it will work fine.
