Segue abaixo o xhtml

O m�todo do rowSelectListener � o abaixo:

    public void rowSelected(SelectEvent event) {
        FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Selected:" + event.getObject().toString(), null);
        FacesContext.getCurrentInstance().addMessage(null, message);

        System.out.println(event.getObject().toString());
    }

    public void rowUnselected(UnselectEvent event) {
        FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Selected:" + event.getObject().toString(), null);
        FacesContext.getCurrentInstance().addMessage(null, message);

        System.out.println(event.getObject().toString());
    }

Agrade�o desde j�.
