by Samba Siva Rao Kolusu (JIRA)

[ https://issues.jboss.org/browse/CDI-682?page=com.atlassian.jira.plugin.sy... ] Samba Siva Rao Kolusu updated CDI-682: -------------------------------------- Description: much like the ability to register beans at runtime through API (https://issues.jboss.org/browse/CDI-114) also provide API BeanManager::unregister("beanName"), or BeanManager::unregister(XYZBean.class) to unregister beans at runtime, and corresponding events (BeforeUnregisteringBean, AfterUnregisteringBean, etc) so that interested listeners can take appropriate actions in the event of a bean getting removed from CDI context. these two together will help build pluggable web applications much like OSGI modules. right now, installing new beans or removing exiting beans requires restart of CDI container, if not web application. with the addition of these two features [registering beans at run time, through BeanManager::register(XYZBean.class) ], and unregistering beans at runtime [BeanManager::unregister(XYZBean.class) ] true modularity comes to Java EE world, without the necessity to restart > Allow de-registration of CDI beans at run time, through API > ----------------------------------------------------------- > > Key: CDI-682 > URL: https://issues.jboss.org/browse/CDI-682 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans, Events, Interceptors > Affects Versions: 1.2.Final > Reporter: Samba Siva Rao Kolusu > > much like the ability to register beans at runtime through API (https://issues.jboss.org/browse/CDI-114) > also provide API > BeanManager::unregister("beanName"), or BeanManager::unregister(XYZBean.class) > to unregister beans at runtime, and corresponding events (BeforeUnregisteringBean, AfterUnregisteringBean, etc) so that interested listeners can take appropriate actions in the event of a bean getting removed from CDI context. > these two together will help build pluggable web applications much like OSGI modules. right now, installing new beans or removing exiting beans requires restart of CDI container, if not web application. with the addition of these two features [registering beans at run time, through BeanManager::register(XYZBean.class) ], and unregistering beans at runtime [BeanManager::unregister(XYZBean.class) ] true modularity comes to Java EE world, without the necessity to restart -- This message was sent by Atlassian JIRA (v7.2.3#72005)

[ https://issues.jboss.org/browse/CDI-682?page=com.atlassian.jira.plugin.sy... ] Matej Novotny edited comment on CDI-682 at 2/1/17 7:15 AM: ----------------------------------------------------------- Also de-registration sounds like an impossible feat because of the static nature of CDI. Things are done at bootstrap and they stay that way during application runtime. Imagine what would happen if you had a {{@Specializes}} bean and tried to de-register that one at runtime. Furthermore, this would result in weird behaviour if you, say, de-register a session scoped bean during active session. was (Author: manovotn): Also de-registration sounds like an impossible feat because of the static nature of CDI.
