[cdi-dev] [JBoss JIRA] (CDI-245) Promote the right way how extensions should communicate with each other during container initialization

[ https://issues.jboss.org/browse/CDI-245?page=com.atlassian.jira.plugin.sy... ] Mark Struberg edited comment on CDI-245 at 8/16/12 8:49 AM: ------------------------------------------------------------ In CDI-1.0 it's just undefined what you can inject at bootup. We can only exclude what explicitely is forbidden or defined to get started afterwards. But there is currently no wording that specifies that e.g. @Stateless beans cannot be @Injected. For Extensions I looked at 11.5: {quote} The container instantiates a single instance of each extension at the beginning of the application initialization process and maintains a reference to it until the application shuts down. The container delivers event notifications to this instance by calling its observer methods. For each service provider, the container must provide a bean of scope @ApplicationScoped and qualifier @Default, sup- porting injection of a reference to the service provider instance. The bean types of this bean include the class of the service provider and all superclasses and interfaces. {quote} Thus a.) all Extensions get loaded before the first container lifecycle event gets fired b.) all Extensions are beans which are available for injection c.) all Extensions are @ApplicationScoped. I guess the problem is that the ApplicationContext only gets started after AfterDeploymentValidation, right? In DeltaSpike we currently use the Extension injection for runtime communication between an Interceptor and it's Extension and not at boot time. was (Author: struberg): In CDI-1.0 it's just undefined what you can inject at bootup.
