问题
We're currently building a web application based on JSF and PrimeFaces and want to use Bean Validation to validate the domain model. The problem we currently face is that we want most error messages displayed next to a single input field. For example, suppose there's a constraint "enddate > startdate", implemented as a class-level bean validator, we still want constraint violations for that rule to show up in a h:message/p:message specific to the enddate field rather than in the globalOnly section. Can this be achieved? If so, how?
