如果我正确理解JSF生命周期,它会在Apply Request阶段注册Validators。 这是否意味着我不能将addValidator调用到我在我的decode()方法中的Component对象句柄中,该方法在Process Request Events阶段被调用?如果是这样,是否有其他方法可以根据组件的属性值动态添加自定义验证器?

我希望应该起作用的是......
public class ValidatorWrapper implements Validator {
private DoubleRangeValidator dbRangeValidator;
private LongRangeValidator lRangeValidator;
private String requiredValidatorType;/*An attribute to choose the type of validator*/
public ValidatorWrapper(){
dbRangeValidator = new DoubleRangeValidator(10.01, 20.99);lRangeValidator = new LongRangeValidator(10, 20);
}
@Override
public void validate(FacesContext context, UIComponent component,
Object value) throws ValidatorException {
if("LONG".equalsIgnoreCase(requiredValidatorType))
lRangeValidator.validate(context, component, value);
else if("DBL".equalsIgnoreCase(requiredValidatorType))
dbRangeValidator.validate(context, component, value);
} }
