    Access to InjectionPoint from custom CDI Context Scope?

    aanderson

      Given a Qualifer @FooId:

       

      @Qualifier                   
      @Target({ ElementType.PARAMETER })                    
      @Retention(RetentionPolicy.RUNTIME)                    
      public @interface FooId {      
        String value(); 
      } 

       

       

      and Custom Scope @FooScope:

       

      @Scope                    
      @Retention(RUNTIME)                    
      @Target(TYPE)                    
      public @interface FooScope {  } 
      

       

       

      and Custom Object Foo:

       

      @FooScope                   
       public class Foo {  }
       

       

       

      and  injection target Bar:

       

      public class Bar {                          
        @Inject                           
        @FooId("0")                           
        Foo foo;                      
      } 

       

       

       

      I would like to have access to the Injection Point foo in Bar so I can read the value of the @FooId annotation and return the appropriately scoped object. While this can be done with providers:

       

       

      @Produces         
      public Foo create(InjectionPoint ip, BeanManager mgr) {
       }

       

       

      there seems to be no way to do this in a custom scope:

       

       

      @Override         
      public <T> T get(Contextual<T> contextual, CreationalContext<T> creationalContext) {         
      }
      

       

       

       

      where contextual is the annotated Bean type. Is this a limitation of CDI and if so will it be addressed in CDI 1.1?

       

      Thanks!
