Hmm, the qualifiers are just used for resolution and are never propagated as such. You are of course free to stuff them into your event payload object if you want them to make the trip.
Wow, my mistake for not checking the forums more regularly. Sorry to leave you unanswered! Nicklas is correct though. We currently don't have any internal objects for wrapping events. In fact, Weld currently does not inform an @Observes injection point of the qualifiers an event was fired on - just that an event with matching qualifiers was fired. So for now we only have minimal information (the explicit qualifiers used to register the event type to forward).

We love feedback!
I would love to help with the project in adding this functionality. If you are ok with me helping out? If so can you send me your details and we can setup a time to chat and figure things out. I have a skype account and can be available anytime to chat :)
