No. It will be delivered to any matching observer method - belongs to an enabled bean, the
event object is assignable to the observed event type and the observer method has all the
event qualifiers (CDI 1.0). In CDI 1.1 qualifier matching rules will likely change:
"The observer method has no event qualifiers or has a subset of the event
qualifiers".
(see 10.2. Observer resolution)

HI Martin,
sure. But will the unmanaged payload be delivered only to observers belonging to the same
scope as the sender?
I didn't found any mention in the spec about that...
thanks,
adam
