Agreed. But in reality in your project, what do think the people do? Build a (complicated) correlation mechanism or hack an action which enables the SIgnalCommand again? ;-)

BTW: In pre-ESB projects we often used the token-id only for correlation, in some circumstances this doesn't cause problems. This is a project based decision. But to have the expected state is definitely best practice, I agree.

But you could have to process flows in parallel, both communicating with the ESB or maybe both flows even communicate with an external partner. Only the token id is unambiguous in this case. In the projects I know I always was fine with the token id.

BTW: Where is the problem with a loop? That doesn't change anything with the token id. Only Fork/Join does...

Don't worry ;-)
