Subject: NEW ISSUE: Composite Scoped components should be able to implementConversational interfaces

Specification
DESCRIPTION:
The resolution of Issue 12 means that
a conversational interface can only be implemented by a conversation scoped
component:
http://www.osoa.org/jira/browse/JAVA-12
This restricts an important use case
for composite scoped components - no longer can composite scoped components
provide
conversational interfaces.
One major reason for having composite
scoped components is that this covers the case of components whose implementations
are expensive to initialize. An
example is an in-memory database component where the loading of the data
might take a
substantial amount of time - done order
to make subsequent queries and updates much faster.
It may well be the case that it is desirable
for such a composite scoped component to be able to offer conversational
interfaces
to its clients. An example is
for an in-memory database component to offer an interface to clients which
provides a cursor into
a large set of data and allow a series
of requests to be issued using that cursor. It seems perverse for
SCA to prevent the use
of these scenarios.
PROPOSAL:
Permit composite scoped components to
implement conversational interfaces.
