[views] Respond with 400 Bad Request in case of validation error in ajax request
Previously, we raised a plain RemoteCallFailed without a status code, in which
case it defaults to "500 Internal Server Error". Now, for validation
errors, we issue a 400 Bad Request since these are clearly client errors.
Additional services
===================
In this chapter, we introduce services crossing the *web -
repository - administration* organisation of the first parts of the
CubicWeb book. Those services can be either proper services (like the
undo functionality) or mere *topical cross-sections* across CubicWeb.
