<p:panel style="height:85px;">

                        </p:cellEditor>
                    </p:column>

这是我的豆子：

@Component("commandeActBeanc")
@SessionScoped
public class CommandeActionBean {

    @Autowired
    private transient ICommandeDao commandeDAO;
    @Autowired
    private transient IPcArticleBoncommandeDao articleCommandeDAO;
    @Autowired
    private transient IProduitDao articleDAO;

    private Integer idBoncommande;
    private Agent agent;
    private ModePayement modePayement;
    private String numero;
    private Boolean isValide;
    private Boolean isSolde;
    private Boolean isImprime;
    private Boolean isSaved;
    private Date dte;

这是我的 ModPayemenActionBean

@Component("modePayementArtBean")
@SessionScoped
public class ModePayementActionBean {

    @Autowired
    IModePayementDao modePayementDao;
    private String intitule;
    private List<ModePayement> modesPayementLista= new ArrayList<ModePayement>();
    /*-----------------------------------Setters et Getters--------------------------------*/


    public IModePayementDao getModePayementDao() {

        return modePayementDao;
    }

    public ModePayementActionBean() {

    }

    public List<ModePayement> getModesPayementLista() {
        modesPayementLista= new ArrayList<ModePayement>();
        modesPayementLista.addAll(getModePayementDao().findAll());
        for (int i=0;i<modesPayementLista.size();i++){
            System.out.println(modesPayementLista.get(i));
        }
        return modesPayementLista;
    }

    public void setModesPayementLista(List<ModePayement> modesPayementLista) {
        this.modesPayementLista = modesPayementLista;
    }

    public void setModePayementDao(IModePayementDao modePayementDao) {
        this.modePayementDao = modePayementDao;
    }

    public String getIntitule() {
        return intitule;
    }

    public void setIntitule(String intitule) {
        this.intitule = intitule;
    }

}

嘿， 你的问题是：你没有在

改变这个：

<p:selectOneMenu value="#{commandeActBeanc.modePayement}">
                        <f:selectItem itemLabel="--" itemValue="" />
                        <f:selectItems value="#{modePayementArtBean.modesPayementLista}" 
                            var="mode" itemLabel="#{mode.intitule}" itemValue="#{mode}" />
                    </p:selectOneMenu>

与：

<p:selectOneMenu value="#{commandeActBeanc.modePayement}" converter="modePayementConvertor">
                        <f:selectItem itemLabel="--" itemValue="" />
                        <f:selectItems value="#{modePayementArtBean.modesPayementLista}" 
                            var="mode" itemLabel="#{mode.intitule}" itemValue="#{mode}" />
                    </p:selectOneMenu>

然后你像这样编写类 modePayementConvertor：

@FacesConverter(value = "modePayementConvertor", forClass = IModePayementDao.class)
public class ModePayementConverter implements Converter {
@Override
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
    Integer target = new Integer(arg2);
/**this use hibernate change it if u like **/
    Session session = ConnectionDb.getInstance().openSession();
    IModePayementDao modePayement= (IModePayementDao) session.get(IModePayementDao.class, target);
    session.close();
    return modePayement;
}

@Override
public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) {
    try {
        return ((IModePayementDao) arg2).getId().toString();
    }
    catch (NullPointerException ex) {
        return "";
    }
}}

为了完成，您必须像这样在 IModePayementDao 中 @Override 方法相等：

/**
 * @see java.lang.Object#equals(java.lang.Object)
 */
@Override
public boolean equals(Object obj) {

    if (obj instanceof IModePayementDao ) {

        if (((IModePayementDao ) obj).getId().equals(this.id)) {
            return true;
        }
        else {
            return false;
        }
    }
    else {
        return false;
    }

}

现在一切正常:)
