Se um dia eu já pedi algo aqui, agora eu estou implorando!

Eu simplesmente não acho o erro nesse código nem à custa de reza braba!

POR FAVOR, se alguém puder me ajudar, agradeço muito! Estou aprendendo JSF sozinho e estou levando um tombo atrás do outro!

Cara, quando vc chama um metodo com ActionListener ele deve ser implementado desta forma:

public void apagaObjeto(ActionEvent event){
lucianotome
lucianotome 
*
      Action Event Handler Method: métodos que recebem um ActionEvent e são void (não procuram nenhuma regra de negação, voltam para a mesma página).
          o Apenas os componentes que implementam ActionSource podem usar esse método.
          o UICommand e UIButton

JSP:

<h:commandLink id="NAmerica" action="bookstore" 
  actionListener="#{localeBean.chooseLocaleFromLink}">

Backbean:

public void chooseLocaleFromLink(ActionEvent event) {

  String current = event.getComponent().getId();

  FacesContext context = FacesContext.getCurrentInstance();

  context.getViewRoot().setLocale((Locale)

    locales.get(current));

}

Olá!

Compreendo o que disse! Eu coloquei uma versão incompatível com que o que está corrente! O fato é que eu já fiz desse jeito também e o erro persiste o mesmo!
