Primefaces selectOneMenu用于阻止其他方法

喜逢身体，我有我使用一个selctOneMenu的问题后，我选择alternativs在服务器端的其他方法从未trigered之一，我ca't弄清楚为什么Primefaces selectOneMenu用于阻止其他方法

这里是我的JSF代码片段

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

         <h:outputLabel 
          style="font: italic;font-family:serif;font-weight: lighter;font-size: x-large;"> 
           Mode de Payement: 
        </h:outputLabel> 

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

       <p:contextMenu for="articles" widgetVar="cMenu"> 
        <p:menuitem value="Edit Cell" icon="ui-icon-search" 
         onclick="PF('BCTable').showCellEditor();return false;" /> 
        <p:menuitem value="Hide Menu" icon="ui-icon-close" 
         onclick="PF('cMenu').hide()" /> 
       </p:contextMenu> 

       <p:dataTable id="articles" var="art" rendered="true" 
        paginator="true" rows="10" style="width:99%;padding-left:8px;" 
        value="#{commandeActBeanc.mediumArticleSuppModel}" editable="true" 
        editMode="cell" widgetVar="BCTable" 
        rowKey="#{art.idArtileBoncommande}" 
        selection="#{commandeActBeanc.selectedArticlesSupp}"> 

        <f:facet name="header"> 
          Commande n° #{commandeActBeanc.cmd.idBoncommande} 
        </f:facet> 

        <p:ajax event="cellEdit" listener="#{commandeActBeanc.onCellEdit}" 
         update=":form:messages,:@this,:form:totaleTtc,:form:totaleHt,:form:totaleTva" /> 

        <p:column selectionMode="multiple" style="width:2%" /> 
        <p:column headerText="code.Art" style="width:15%"> 

          #{art.codeArticle} 

        </p:column> 

        <p:column headerText="Libelle.Art" style="width:15%"> 

           #{art.referenceArticle} 

        </p:column> 

        <p:column headerText="P.U en TTC" style="width:15%"> 
         #{art.prixUnitTtc} 
        </p:column> 

        <p:column headerText="Quantité" style="width:15%"> 
         <p:cellEditor> 
          <f:facet name="output"> 
           <h:outputText value="#{art.quantite}" /> 
          </f:facet> 
          <f:facet name="input"> 
           <p:inputText value="#{art.quantite}" style="width:96%" 
            label="Quantite" /> 

          </f:facet> 
         </p:cellEditor> 
        </p:column>

，这里是我的豆：

@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; 
    } 

}

海兰，你的问题是：你有没有在

变化做一个转换器这样的：

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

有：

<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>

之后，你肥大写类modePayementConvertor是这样的：

@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 ""; 
    } 
}}

和终点必须@Override这样在IModePayementDao的梅索德等于：

/** 
* @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:)
