  | Yeah, I was wondering about that too.  Surely the action name is all that's needed and that only needs to be unique on a per service basis, right?

So you're saying that you will never want to deploy multiple actions of the same type within the same chain? Seems like an artifical limitation, but maybe I'm missing something ;-)?

As long as the instance name contains enough information to identify the type of the action, then I don't see a problem. What I was thinking in terms of:


  | <action type>:<action instance id>
  | 

was that the action type might be something meaningful like DebugAction, whereas the action id could be a UID.

But all of this is syntactic sugar. As long as we can uniquely and meaningfully identify actions within a chain!

Yes, I agree. That's what I meant earlier when I said that however we name/identify these things has got to be done so that the user can immediately see what's going on. We don't want any of "OK, so BARFOO is the nickname; let me pop up my editor and check the esb.xml and see what that relates to" ;-)
