Barry Woods commented on ISIS-256:
----------------------------------
Resolution:
1. Added a check for optional facet. If field is mandatory and not supplied now
throws and IllegalArgumentException
2. Flags the the error field with an invalidReason of consent.getReason() and
continues processing remaining fields
Did consider just silently ignoring any value supplied but decided this was a
more complete approach. Downside is that any getter only fields will need to be
annotated @Optional before the object can be persisted.
