錯誤空指針JSF傳輸數據

我在這裏做了這段代碼，q旨在列出銀行的值，並且用戶可以通過dataTable更新日期。到目前爲止，我設法達到了這一點，只有這樣，才能設置用戶輸入的值。我無法在世界任何地方找到這個值，已經運行了tdo，並且輸入框中的值不會出現。我使用了幾種類型的變量，但沒有。錯誤空指針JSF傳輸數據

<p:dataTable id="dataTable" 
          var="Arquivo"

          > 
        <p:column headerText="ID">

              update=":form:dataTableProd" 
              onclick="listarProd([{name: 'ArquivoId', value:#{Arquivo.id}}]);">

         </h:form> 
        </p:column> 
        <p:column headerText="Data" > 
         <p:inputMask id ="entrada#{cc.clientId}" mask="99/99/9999" value="#{Arquivo.dataEntrada}" 
            onkeypress="if (event.keyCode === 13) { 
                 test([{name: 'ArquivoId', value:#{Arquivo.id}}]); 
                 return; 
                };" 
            size="8">

         </p:inputMask> 
        </p:column> 
       </p:dataTable>

多閒逛之後，我發現鉻的這個錯誤檢查的元素，標籤網絡：

<partial-response id="j_id1"><error><error-name>class java.lang.NullPointerException</error-name><error-message><![CDATA[]]></error-message></error></partial-response>

創建/安裝體面的ajax異常處理程序並重試。它應該給你完整的堆棧跟蹤和原因的線索。 JSF實用程序庫OmniFaces有這樣的一個：http://showcase.omnifaces.org/exceptionhandlers/FullAjaxExceptionHandler – BalusC

對不起，但我有錯誤是由於豆的結果，而不是事務。問題是我不能設置h：InputMask的值，另一個想法？ –

我固定取出型塊，並把多種形式到位的需求。只是它使作品。
