下拉列表不顯示在primefaces數據表列過濾器框中

Question

我正在使用Jsf 2.2和primefaces 4.0。當我使用這個代碼時一切正常。

<p:column headerText="Status" filterBy="#{List_request.rechargeStatusName}" filterMatchMode="contains" > 

      <h:outputText value="#{List_request.rechargeStatusName}" /> 
</p:column> 

但是當我嘗試在此列中的過濾器框中加載下拉列表時。 而寫這樣的代碼

<p:column headerText="Status" filterBy="#{List_request.rechargeStatusName}" filterMatchMode="contains" > 
          <f:facet name="filter"> 
           <p:selectOneMenu value="#{List_request.rechargeStatusName}" onchange="PF('reTab').filter()"> 
            <f:selectItem itemLabel="-Select One-" itemValue="#{null}" noSelectionOption="true" /> 
            <f:selectItems value="#{allRequestDetailsBean.rechargeStasusNameList}" /> 
           </p:selectOneMenu> 
          </f:facet> 
          <h:outputText value="#{List_request.rechargeStatusName}" /> 
      </p:column> 

然後下拉列表中沒有過濾箱和過濾顯示不工作-------- Plase幫助任何人。

Answer 1

過濾方面不是在4.0支持...（查看文檔，檢查blog看的時候加入它等）

Answer 2

由於過濾切面不可用4.0，你可以使用<p:column的filterOptions，剛剛創建的SelectItem[]陣列，相關的值，並將其放置在你的filterOptions

例如：

<p:column filterBy="#{car.manufacturer}" 
    headerText="Manufacturer" footerText="exact" 
    filterOptions="#{tableBean.manufacturerOptions}" 
    filterMatchMode="exact"> 
    <h:outputText value="#{car.manufacturer}" /> 
</p:column> 


private SelectItem[] manufacturerOptions; 

...

manufacturers = new String[10]; 
    manufacturers[0] = "Mercedes"; 
    manufacturers[1] = "BMW"; 
    manufacturers[2] = "Volvo"; 
    manufacturers[3] = "Audi"; 
    manufacturers[4] = "Renault"; 
    manufacturers[5] = "Opel"; 
    manufacturers[6] = "Volkswagen"; 
    manufacturers[7] = "Chrysler"; 
    manufacturers[8] = "Ferrari"; 
    manufacturers[9] = "Ford"; 

public SelectItem[] getManufacturerOptions() { 
    return manufacturerOptions; 
}
