af:inputtext set to lowercase?

Question

I have an <af:inputtext> box that is accepting an e-mail address. This e-mail address is one of the search items for the query, which is working fine. However, I need to make it to a lower case string before it is being sent to the query.
I tried to make a validator which returns the right result using the toLowerCase() java function, but that value is not being processed to the query. I also tried to do the same action in the button event to validate it but again, I can't seem to get it to work.
This seems like it should be easy but I'm lost at the moment.

You need custom convertor to make it lowercase.
import java.util.Collection;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import org.apache.myfaces.trinidad.convert.ClientConverter;
public class UppercaseConverter implements Converter, ClientConverter {
    public Object getAsObject( FacesContext facesContext, UIComponent component, String stringValue) {
        return stringValue.toLowerCase();
    public String getAsString(FacesContext facesContext, UIComponent uiComponent, Object objectValue) {
        return objectValue.toString();
    public String getClientLibrarySource(FacesContext context) {
        return context.getExternalContext().getRequestContextPath() + "/scripts/FieldAsLowercase.js";
    public Collection<String> getClientImportNames() {
        return null;
    public String getClientScript(FacesContext context, UIComponent component) {
        return null;
    public String getClientConversion(FacesContext context, UIComponent component) {
        return ("new FieldAsUppercase()");
function FieldAsLowercase() {
    this._class = "FieldAsUppercase";
FieldAsLowercase.prototype = new TrConverter();
FieldAsLowercase.prototype.getFormatHint = function() {
    return null;
FieldAsLowercase.prototype.getAsString = function(string,label) {
    return string.toLowerCase();
FieldAsLowercase.prototype.getAsObject = function(string,label) {
    return string.toLowerCase();
}
