Subject: RE: [wsbpel] New Issue - Link Semantics in Event Handlers
Yuzo, Thank you for the example. It seems that in that specific case, each message would create a new flow activity. So if you have 4 messages, you end up with 4 instances of the flow activity (all running concurrently). Each flow activity instance will have its own AtoB link. No?
