Hi John, Bean.getInjectionPoints() is only used during validation - returned injection points are validated at initialization time, so for a custom bean it makes sense to return an empty set as there are no real injection points. WRT lookup - what exactly do you try to accomplish? Do you try to obtain InjectionPoint metadata from inside a custom dependent bean's create() method? This should be possible although not clearly specified. I think we have a test with BeanManager.getInjectableReference(InjectionPoint, CreationalContext<?>) but I will need to double check. I will also look at the geronimo-config repo. Martin Dne 4.8.2017 v 11:42 John D. Ament napsal(a): > Hi > > As the subject says.

Martin, Knowing that I don't have any reference to an injection point, what would you recommend I pass in as a dummy injection point?

Contextual reference for a bean [1]: "The container must ensure that every injection point of type InjectionPoint and qualifier @Default of any dependent object instantiated during this process receives a null value if it is not being injected into any injection point." However, in Weld you could use BeanManager.getInjectableReference(InjectionPoint, CreationalContext<?>) and provide some dummy IP. See for example https://github.com/weld/core/blob/master/tests-arquillian/src/test/java/o.... FYI there is a TCK test that verifies the InjectionPoint is null if using getReference() outside custom bean's create: org.jboss.cdi.tck.tests.lookup.injectionpoint.InjectionPointTest#testNullInjectionPointInjectedIntoNonInjectedObject() Martin [1] http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#contextual_reference Dne 4.8.2017 v 13:05 Martin Kouba napsal(a): > Hi John, > > Bean.getInjectionPoints() is only used during validation - returned > injection points are validated at initialization time, so for a custom > bean it makes sense to return an empty set as there are no real > injection points. > > WRT lookup - what exactly do you try to accomplish?
