-------------------------------------
That sounds strange, maybe there is a problem with the class path, duplicated
jar files or somthing else. If your class implements
javax.faces.validator.Validator java would be able to cast. I belive the bug is
not up to myfaces.
> JSF Validator cannot be cast to javax.faces.validator.Validator

> cannot be cast to javax.faces.validator.Validator
> at
> org.apache.myfaces.application.ApplicationImpl.createValidator(ApplicationImpl.java:613)
> The code of my validator is:
> ==========================================================
> package com.kachanov.test004.validators;
> import javax.faces.application.FacesMessage;
> import javax.faces.component.UIComponent;
> import javax.faces.context.FacesContext;
> import javax.faces.validator.Validator;
> import javax.faces.validator.ValidatorException;
> public class MyValidator implements Validator {
> public void validate(FacesContext arg0, UIComponent arg1, Object arg2)
> throws ValidatorException {
>
> System.out.println("testing this validator");
> }
> }
> ==========================================================
> So please thell me how can it bee that a class that implements Validator
