As we are both being nightowls in the same timezone, let me continue with
this. We are using a Broker. So, in my case each Action would call the
Broker, which is our link to the enterprise layer. Also, if the business
object rejected the data, as you said, than it would pass it to the Action
but NOT up again to the ActionForm. At that point the Action would choose a
forward with errors and data.
