I'm creating a small Pub/Sub flow that will take a message break into multiple messages and publish each to it's associated subscrber. The catch is the affinity of the composite message needs to be maintained i.e. the order of the individual messages that come out of the composite needs to be maintained. The problem is if/when the flow fails in the middle of processing a composite ... some of the individual messages will make it to their subscribers while the others will fail.

My solution was to resend the original message once the flow was back up but that would mean sending duplicate messages to the subscriber which isn't an option. I've heard using the transactional function in WMB is tricky at best and was hoping there might be another solution?

Thank you,
Scott
