Lou Amodeo commented on TUSCANY-1046:
-------------------------------------
I do not think that I am exactly past this problem. It makes sense to me to
annotate with @Scope("CONVERSATION') on the implemmentation class to designate
a specific services instances should be managed as conversational by the
container. I am unclear what is required on the client interface to indicate
to the client runtime that a conversation needs to be started. Are we saying
that for now @Scope("CONVERSATION") is required on the interface as well and
that a new annotation will be defined to the spec in the future? Is it
valid to have a conversational client interface but not the service impl and
vice- versa? It also appears that there is no validation of the annotations by
the runtime and when annotations are misplaced or not synchronized
inappropriate exceptions may be thrown as in this instance.
