Jasper,

Well...I don't think there is a hard and fast rule here. Trying to add a
customer that already exists could be a read as a client error (they
shouldn't do it) or a server error (we won't let you do it). But either way,
5xx errors (at least at the SOAP level) are *not* just about the server
going down for maintenance...and how could it tell anyone? ;)

Anyway, the main point is it is currently defined, XForms would ignore the
XML returned in the SOAP message for any error returned, *including* 4xx
ones. Obviously a big problem, since SOAP over HTTP defines that an XML
payload will be present for nearly all return codes.

Regards,

Mark

Wouldn't it make more sense to send a 4xx error in that example, since
the fault is with something the client did (trying to add a customer
that already exists) rather than something the server did (e.g. going
down for maintenance)?
