Segue abaixo o xhtml
O método do rowSelectListener é 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());
    }
Agradeço desde já.
