Integration Layer question: Is there a way to correlate an Invoke with a previous Receive?

[Mike Edwards]

Folks,

In implementing BPEL support in Apache Tuscany, I find that I have a need to correlate a message 
received by a BPE Process through a RECEIVE statement with a later message transmitted from the same 
Process instance by an INVOKE statement.

Is there some way in which the Integration Layer can do this?  eg is there a way to get at the 
process instance ID from both the MEX used for the RECEIVE and also from the MEX used for the INVOKE?


Many thanks,


Yours,  Mike.
