validator for custom components in JSF fails - jsf-2

Question

In my custom component, I have
<composite:interface>
<composite:editableValueHolder name="val_pwd" targets="form:pwd"/>
<composite:attribute name="name" required="true"/>
.....
</composite:interface>
<composite:implementation>
<h:form id="form">
<h:panelGrid columns="3">
<h:outputText value="#{cc.attrs.namePrompt}" />
<h:inputText value="#{cc.attrs.name}" id="name"/>
<h:outputText value="#{cc.attrs.passwordPrompt}" />
<h:inputSecret value="#{cc.attrs.pwd}" id="pwd"/>
<h:commandButton value="#{cc.attrs.submitButtonValue}" action="#{cc.attrs.actionMethod}"/>
</h:panelGrid>
</h:form>
</composite:implementation>
I have a validator,
#FacesValidator("passwordVal")
public class PasswordValidator implements Validator {
public PasswordValidator() {
super();
}
#Override
public void validate(FacesContext facesContext, UIComponent uIComponent, Object object) throws ValidatorException {
if(object instanceof String){
String s = (String) object;
if(s.contains("#"))
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error","Password cannot have #"));
}
}
}
In my JSF page, I have
<h:body>
<util:ccwithcustomval namePrompt="r_Name" passwordPrompt="r_pwd" name="#{person.name}"
pwd="#{person.pwd}" actionMethod="#{person.action}" submitButtonValue="r_submit">
<f:validateLength for="val_name" maximum="5"/>
<f:validator validatorId="passwordVal" for="val_pwd" />
</util:ccwithcustomval>
</h:body>
However, it fails with exception
InputComponent.xhtml #12,60 <f:validator> ADF_FACES-60085:Parent not an instance of
EditableValueHolder: javax.faces.component.UINamingContainer#4e18afaa
The problem is with my validator, if I comment it out the page displays
