[cdi-dev] [JBoss JIRA] (CDI-219) Support Request Scope for EJB @Singleton @PostConstruct methods

Fri Aug 31 05:46:33 EDT 2012

    [ https://issues.jboss.org/browse/CDI-219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715080#comment-12715080 ] 

Guido Bonazza commented on CDI-219:
-----------------------------------

Doesn't the TransactionContext (see CDI-121) already violate this principle? I suppose that, if a transaction is suspended and a new one is begun, the corresponding context is suspended as well and a new one is created/activated. I'm just guessing here about TransactionContext so maybe I'm wrong, but it seems to me that the threading semantics of CDI 1.0 is a bit limiting.

> A Request context should be available in @PostConstruct methods of EJB Singletons.
> This is a completion of section 6.7.1 of the CDI 1.0 spec, which covers @Asynchronous and @Timeout EJB methods.
> Probably the container should ensure that a new context is always created for the @PostConstruct invocation, to be coherent with section 4.8.3 of the EJB 3.1 spec, which specifies the transactional behavior of @Singleton @PostConstruct.
