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?
