[cdi-dev] [JBoss JIRA] (CDI-78) Clarify how isDelegate() behaves on InjectionPoint, and what happens when an InjectionPoint is injected into a Decorator

[Jozef Hartinger (JIRA)]

    [ https://issues.jboss.org/browse/CDI-78?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712667#comment-12712667 ] 

Jozef Hartinger commented on CDI-78:
------------------------------------

The tricky part of having

{code:JAVA}
@Inject
InjectionPoint ip
{code}

in a Decorator is that one may have multiple decorated beans such as:

{code:JAVA}
public class Foo implements Readable {

   public int read(CharBuffer cb) {
      return 0;
   }
}

@ApplicationScoped
public class Bar implements Readable {

   public int read(CharBuffer cb) {
      return 0;
   }
}
{code}

Both beans would be decorated by a decorator:

{code:JAVA}
public class ReadableDecorator implements Readable {

   @Inject @Delegate
   Readable delegate;

   @Inject
   InjectionPoint ip;

   public int read(CharBuffer cb) {
      return delegate.read(cb);
   }
}
{code}

The problem is that there is no InjectionPoint metadata to be injected into decorator when the normal-scoped bean (Bar) is decorated. At the same time there is no problem decorating Foo since it is dependent and InjectionPoint metadata is available.

> The InjectionPoint should be that of the injection into the consumer, and isDelegate() should return false.
