Subject [jira] Created: (MYFACES-1829) JSF Validator cannot be cast to javax.faces.validator.Validator
Date Sun, 02 Mar 2008 15:32:50 GMT
JSF Validator cannot be cast to javax.faces.validator.Validator

                 Key: MYFACES-1829
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 1.1.5
         Environment: JBoss Portal - Identity portlet
            Reporter: Alex Kachanov

JBoss portal is using idenityt portlet to regster new users and edit  profiles for existing
I added new my own JSF validator to the identty portlet which when opened throws the following

java.lang.ClassCastException: com.kachanov.test004.validators.MyValidator cannot be cast to
	at org.apache.myfaces.application.ApplicationImpl.createValidator(

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 cannot be cast to
Is in't it against basic design of Java languages?
