public class DynamicValidatorHandler
extends javax.faces.view.facelets.ValidatorHandler

Adds dynamic evaluation of attributes to validators.
Normally the attributes of validators are not dynamically evaluated at runtime, but this handler evaluates all attributes, just before validation.
Usage: Simply add this handler to your facelet-taglib file like this:
<handler-class>org.josef.web.jsf.validator.DynamicValidatorHandler</handler-class>
Current limitation: Only handles get/set methods. is or has for a boolean property is currently not supported.
