Question

我有一个带有incell编辑的数据表，可以正确显示记录但是当我尝试编辑一行时，不会反映出这种变化。以下是xhtml代码：

 <p:cellEditor>
            <f:facet name="output">
                <h:outputText value="#{scrip.companyName}"/> 
            </f:facet>
           <f:facet name="input">
               <p:inputText value="#{scrip.companyName}"/> 
            </f:facet>
            </p:cellEditor>
        </p:column>
            <p:column headerText="Exchange">
            <p:cellEditor>
            <f:facet name="output">
              <h:outputText value="#{scrip.exchange}"/> 
            </f:facet>
                <f:facet name="input">
            <p:selectOneMenu style="width: 150px" value="#{manageScrip.exchange}">
                <f:selectItem itemLabel="nse" itemValue="nse"/>
                <f:selectItem itemLabel="bse" itemValue="bse"/>                        
            </p:selectOneMenu>
                    </f:facet>
       </p:cellEditor>
        </p:column>
            <p:column headerText="Brokerage Charge">
            <p:cellEditor>
            <f:facet name="output">
           <h:outputText value="#{scrip.brokerageCharge}"/> 
            </f:facet>
           <f:facet name="input">
           <p:inputText value="#{scrip.brokerageCharge}"/> 
            </f:facet>
       </p:cellEditor>
        </p:column>

            <p:column headerText="Options">
                <p:rowEditor/>

        </p:column>

    </p:dataTable>

    </h:form>
</h:body>

以下是托管bean函数：

public void updateScrip()
{
    try{
        Integer i=(Integer)dt.getRowKey();
        String str=i.toString();
        sc=(ScripMaster) dt.getRowData(str);

        scripSymbol=sc.getScripSymbol();
        exchange=sc.getExchange();
        companyName=sc.getCompanyName();


        updateScrip(i, scripSymbol, companyName, exchange,);

      }catch(Exception ex){

        }
}

或者我也尝试过：

public void updateScrip(RowEditEvent e)
{
    try{
        sc=(ScripMaster) e.getObject();
        scripSymbol=sc.getScripSymbol();
        exchange=sc.getExchange();
        companyName=sc.getCompanyName();
        Integer i=sc.getScripID();
        updateScrip(i, scripSymbol, companyName, exchange);
        }catch(Exception ex){
        }
}

Answer 1

最重要的部分是缺少数据表标记。

确保“editable”属性设置为true。我认为这个属性是在3.2版本中发明的，使许多onld数据表不可编辑。

Answer 2

尝试使用h:inputText代替p:inputText。

primefaces 3.2数据表incell编辑不起作用
