Localization and change language action

Question

Hi, I am facing the following problem... I wish to provide a web application with the option of changing the language. I have included two bundle.properties files (bundle_en and bundle_el) and both of them work fine when changing the default language in by browser. However I cannot change the language at runtime with a command button i have added. This is the relevant code..
faces-config.xml
<application>
<message-bundle>javaserverfaces/Bundle</message-bundle>
<locale-config>
<default-locale>en</default-locale>
<supported-locale>en</supported-locale>
<supported-locale>el</supported-locale>
</locale-config>
</application>
<managed-bean>
<display-name>LanguageSelect</display-name>
<managed-bean-name>LanguageSelect</managed-bean-name>
<managed-bean-class>org.netbeans.javaserverfaces.LanguageSelect</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
header.jsp
<h:commandButton value="#{msg.LanguageButton}" styleClass="language-select-button" actionListener="#{LanguageSelect.changeLanguage}"/>
LanguageSelect.java
public class LanguageSelect implements ActionListener {
/** Creates a new instance of LanguageSelect */
public LanguageSelect() {
public void changeLanguage(ActionEvent event) {
FacesContext facesContext = FacesContext.getCurrentInstance();
Locale locele = (Locale) facesContext.getViewRoot().getLocale();
System.out.println("setting locale to English");
facesContext.getViewRoot().setLocale(new Locale("en"));
String viewId = facesContext.getViewRoot().getViewId();
int lastSlash = viewId.lastIndexOf("/");
try {
facesContext.getExternalContext().redirect(viewId.substring(lastSlash+1));
} catch (IOException ex) {
ex.printStackTrace();
System.out.println("locale set to English");
public void actionPerformed(java.awt.event.ActionEvent e) {    }
Any help would be appreciated, thanks...

I think it's this answer comes late for you, but If anyone it's interested, we use (in version 10.1.4) this function:
PORTAL.wwctx_app_language.set_language(p_http_language => 'es-es',
                                                       p_nls_language => PORTAL.wwnls_api.SPANISH,
                                                       p_nls_territory => PORTAL.wwnls_api.TER_SPAIN,
                                                       p_requested_url => url);
Where 'url' is the url you want to come back.
Remember you can call any function/procedure by the url: /portal/pls/porta/squema.name_of_the_proc, where you have to substitute squema and name_of_the_proc by tyhe ones you need to call (don't forget privileges).
Good luck
