[cdi-dev] [JBoss JIRA] (CDI-610) Add API to obtain current injection point from Bean#create

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-610?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245143#comment-13245143 ] 

Martin Kouba commented on CDI-610:
----------------------------------

bq. For the Bean<T> case this would surely work as well...

Which other cases do you have in mind? I wouldn't add this to the {{BeanManager}}. I think it's bound to the lifecycle of a {{@Dependent}} bean.

bq. It should be as much aligned with injecting the InjectionPoint in a producer method.

Not only producer methods but any {{@Dependent}} bean is allowed to obtain the injection point.

bq. I don't know from the top of my head...

Yes, it's a definition error.

> There's currently not a clear way on how to obtain the *current* injection point (if any) from {{Bean<T>#create}}.
> A previously somewhat accepted way (though not specified) was:
> {code}
>   Bean<? extends Object> bean = beanManager.resolve(beanManager.getBeans(InjectionPoint.class));
>   InjectionPoint injectionPoint = (InjectionPoint) beanManager.getReference(bean, InjectionPoint.class, creationalContext);
> {code}
> This however broke in some version of Weld.
> Since getting the injection point is an often used feature in producers, I'd like to propose to introduce an easy API for this, so {{Bean<T>}} implementations can use this just as easily. E.g. something like: {{BeanManager#getCurrentInjectionPoint()}}.
