[seam-dev] Seam REST and WELD-001303 No active contexts

I agree that Conversations should be supported for other connections
besides JSF, however, with REST or any web service call there is a problem
about tying a request to a session, you'd either have to have the client's
support sending cookies in their requests or create store like a session
yourself. If you go with the latter approach then it should be fairly easy
to (well, as easy as creating passivation capable scopes is) to create a
scope that would work with this cache / store.

If it is a regression, please create a JIRA with attached Arquillian
test(s).
