Are you using Weld 1.0.1 - I fixed this there IIRC.

The InjectionPoint of the producer lacked the additional selected annotations.  I'm trying to create a TopicProducer and need to dynamically inject a topic.  When the topic producer is invoked the InjectionPoint does not contain the JmsDestination (the annotations are only @Inject and @Any, which seems like @Inject shouldn't be there either).  Is there a better way to do this?
