[cdi-dev] Scoped CDI Events?

[Martin Kouba]

Hi Adam, Arne,

The built-in Event bean is not stateless, it's @Dependent. The event payload - the event object - is really not managed and thus not scoped (and should not be IMHO). I also think the event object should be immutable since the order in which observer methods are called is not defined...
