> In JSR303 § 4.2 ConstraintViolation, there is the following note:
>   "From rootBean and propertyPath, it is possible to rebuild the context of the failure"
> Perhaps it would be possible for graphValidator to map ConstraintViolation propertyPath to ValueExpressions, then iterate child EditableValueHolder components and assign FacesMessages to clientIds of these components where it finds a match, otherwise fallback on the current behavior of using the clientId of the graphValidator itself (perhaps even adding an the option to use a null clientId for global messages instead).
> A more thorough example of this use-case is here: http://stackoverflow.com/questions/5639088/cross-field-validation-with-inline-messaging-in-jsf-with-jsr-303
> Comments at stackoverflow suggest MyFaces ExtVal Bean Validation can do the trick, however I went down that road, their framework ignores ConstraintViolation propertyPath as well (see: http://old.nabble.com/Re%3A-ExtVal-BV-question-to33455513.html)
