        Sorry, a noob question here, can I test against the latest nightly build to try you fix?

        Yes, you can. The binaries are available for download. Follow this thread http://community.jboss.org/thread/167590

          I tried a nightly build (16 Jul 2011), and the problem seems solved, until I hit a variant of the same problem...

           

          Basically, I had several business interfaces that had some common methods (such as count), hence I had a super interface called FacadeLocal. See following codes:

           

          public interface FacadeLocal<T> {
              int count();
          }
          
          public interface VehicleFacadeLocal extends FacadeLocal<T> {
              //inherits all parent interface methods
          }
          
          public abstract class AbstractFacade<T> {
              private Class<T> entityClass;
          
              public AbstractFacade(Class<T> entityClass) {
                  this.entityClass = entityClass;
              }
          
              protected abstract EntityManager getEntityManager();
          
          }
          
          @Stateless
          public class VehicleFacade extends AbstractFacade<Vehicle> implements VehicleFacadeLocal {
              @PersistenceContext(unitName = "testfacadePU")
              private EntityManager em;
          
              protected EntityManager getEntityManager() {
                  return em;
              }
          
              public VehicleFacade() {
                  super(Vehicle.class);
              }
          
          }
          
          @Named
          @SessionScoped
          public class WebBean implements Serializable {
          
              @Inject
              private VehicleFacadeLocal vf; //calls the business interface instead of implementation
          
              public int getVehicleCount() {
                  return vf.count();
              }
          }
          
          

           

          Now when I run, I get an exception that says View of type interface x.y.FacadeLocal not found on bean.

           

          I believe it is the same problem, but any use case. Since I have a lot of business interfaces, which quite a number of common ones, this implementation would be important to me.

           

          Hoping for help, thanks!

            If the latest build has the same issue, please post the entire exception stacktrace.

              I haven't been able to download the nightly build, seems like the site is down or has exceed maximum number of connections.

               

              Anyway, I did some digging, and realised Glassfish 3.1.1 had the same issues. However, after changing the @Inject to @EJB instead, both Glassfish and JBoss 7 (nightly - 17 Jul) worked.

               

              I'll try out the latest nightly before posting a full stacktrace.
