Ignacio Silva-Lepe commented on TUSCANY-1046:
---------------------------------------------
For conversations, the annotation can be used on both the interface, to denote
a conversational contract with the client, and the implementation, to indicate
to the component's container to keep track of the component's conversational
state. So, depending on the scenario, both uses can occur at the same time. The
loanappconversation sample does this, for instance. I agree that the wording of
the spec does not reflect this, so it most likely will be changed.
Since you are past the problem, I assume that this issue can be closed?
