JSF 2.1 conditional field validation

Question

I have the following JSF 2.1 page

<h:selectOneRadio value="#{userBean.newUser}">
    <f:selectItem itemValue="0" itemLabel="new User" />
    <f:selectItem itemValue="1" itemLabel="existing User" />
</h:selectOneRadio>
<br />
<h:inputText value="#{userBean.customerId}" id="customerId" />
<h:message for="customerid" />
<br />
<h:inputText value="#{userBean.firstName}" id="firstName" />
<h:message for="fisrtName" />
<br />
<h:inputText value="#{userBean.lastName}" id="lastName" />
<h:message for="lastName" />
<br />
<h:commandButton value="Submit" action="#{userBean.login}" />

and this is my bean:

public class UserBean {

    private String customerId;
    private String newUser= "0";
    private String firstName;
    private String lastName;

    // Getters and seeters ommited.
}

I need to check this form as follows:

If the “new user” radio button is selected, all input data of the form must be checked. If "existing user" is selected, I only need to check the client ID.

I tried Hibernate Validation, and I also tried my own validator by implementing the interface javax.faces.validator.Validator.

Is it possible to somehow achieve this functionality?

, . . , ExtVal @SkipValidation?

@SkipValidation("#{person.role eq 'admin'}")
@Required
@Equals("person.password")
@NotEquals("password")
private String oldPassword;
