Question

我无法弄清楚为什么我的primefaces民意调查不会更新任何组件。

<p:poll widgetVar="poll" 
                            interval="#{messageBean.refreshInterval}" 
                            listener="#{messageBean.refreshLiveData}" 
                            update=":transactionLogForm:tabViewMain:liveViewPanel"/>

成功调用了refreshLiveData方法，但它拒绝更新outputText组件（或任何组件）。

                        <p:tab id="liveViewTab" title="Live View">
                            <h:panelGrid id="liveViewPanel" columns="6" cellpadding="5">
                                <h:outputText value="Live View Enabled: " />  

                                <p:selectBooleanCheckbox value="#{messageBean.liveViewActive}">  
                                </p:selectBooleanCheckbox> 

                                <h:outputText value="Interval: " />  
                                <p:spinner id="interval" value="#{transactionLogBean.refreshInterval}" />  
                                <h:outputText value="Last Update:" />  
                                <h:outputText id="lastUpdated" value="#{transactionLogBean.lastUpdated}" />  
                            </h:panelGrid>
                        </p:tab>

以下是body标签内的完整代码：

我没有收到任何错误报告，因此所有引用都必须正常 - 请帮忙！我正在使用JSF 2.0，Primefaces 3.4.RC1

问题解决了 - 毕竟这是一个支持bean的问题，与调查本身无关，而且工作正常。
