[seam-dev] Postconstruct issue when registering a Bean in an extension

Hi All, In Seam Social, in order to support polymorphism I need the service beans to be qualified with the name of the service. For instance : @RelatedTo("LinkedIn") public class LinkedInJackson extends OAuthServiceBase implements LinkedIn It allows users to inject a service bean like that @Inject @RelatedTo("LinkedIn") OAuthService service; As I want to ease user life I also need to support this kind of injection (same results as above) @Inject LinkedIn service; As LinkedIn interface has only one implementation, using a qualifier when I use its specific type is useless and could be confusing. Until now I registered the second version of the bean (without a qualifier) thru a producer, but as each service bean will have both registration (with and without qualifier) I decided to simplify this bi-registration with an extension (it will also ease the writing of new service bean for third party developers). My extension works in 2 steps : First it collects in a Map all the annotated type which are OAuthService children and have a @RelatedTo qualifier : public void processServicesBeans(@Observes ProcessManagedBean<OAuthService> pbean) { Annotated annotated = pbean.getAnnotated(); if (annotated.isAnnotationPresent(RelatedTo.class)) { RelatedTo related = annotated.getAnnotation(RelatedTo.class); String name = related.value(); servicesBean.put(name, pbean.getAnnotatedBeanClass()); } } Then, after the bean discovery, it register a new version of each Qualified bean without the qualifier (thanks to solder !). public void afterBeanDiscovery(@Observes AfterBeanDiscovery abd, BeanManager bm) { for (String type : servicesBean.keySet()) { AnnotatedType<? extends OAuthService> annotatedType = servicesBean.get(type); AnnotatedTypeBuilder annoBuilder = new AnnotatedTypeBuilder().readFromType(annotatedType).removeFromClass( RelatedTo.class); AnnotatedType myAnnotatedType = annoBuilder.create(); BeanBuilder beanBuilder = new BeanBuilder(bm).readFromType(myAnnotatedType); abd.addBean(beanBuilder.create()); } } This seems to work quite well except that my service Beans have a @Postconstruct method and at initialization Weld throws the following exception org.jboss.weld.exceptions.DefinitionException: WELD-000805 Cannot have more than one post construct method annotated with @PostConstruct for public class org.jboss.seam.social.linkedin.LinkedInJackson If I remove the @Postconstuct in the AnnotatedTypeBuilder by changing its declaration by : AnnotatedTypeBuilder annoBuilder = new AnnotatedTypeBuilder().readFromType(annotatedType).removeFromClass( RelatedTo.class).removeFromAll(PostConstruct.class); Initialization works, I have my 2 beans, but the one I registered without qualifier won't execute the @PostConstruct method (since I had to remove it). I guess I'm missing something in the CDI meta-meta-maze :-). Any help or suggestion would be nice. Thanks, Antoine SABOT-DURAND
