Subject: Issue 250 - autowire

Eric
I don't think that the fact that something
has been defined for service/references necessarily means we have to have
it for events. We already have indirection between the event producers
and consumers via channels, so I would like to explore what the problem
is with channels.
In your description of 250, you indicate
that some sort of scoping mechanism is required, to avoid a complete free
for all - but isn't that just what channels are intended for? If you want
free exchange of events between any producer and consumer you just attach
them to a global channel - for example the default domain channel which
is provided for exactly this purpose. If you want to restrict the scope
to the local composite, you attach them to a local channel.
Is the issue here that you see a need
for scopes somewhere in between these two extremes? This, incidentally,
is something I think also underlies the 227 question.
