這裏有更多的代碼

<h:panelGrid columns="2" style="margin-bottom:10px" cellpadding="5"> 
    <p:outputLabel for="selectone" value="Upload :" /> 
    <p:selectOneRadio id="selectone" 
         value="#{tweetDistributionManagedBean.tweetType}"> 
     <f:selectItem itemLabel="Group Tweets" itemValue="GT" /> 
     <f:selectItem itemLabel="Event Tweets" itemValue="ET" /> 
     <f:selectItem itemLabel="Suprachar Tweets" itemValue="ST" /> 

     <p:ajax event="click" 
       listener="#{tweetDistributionManagedBean.renderUploadPanel}" 
       update="gtid" process="@form" global="false" /> 
    </p:selectOneRadio> 
</h:panelGrid> 

和Java bean的方法

public void renderUploadPanel(final SelectEvent event) { 
    String selecteValues = (String) event.getObject(); 
    visibleGTFlag = true; 
} 

Answer 1

試試這個

public void renderUploadPanel(AjaxBehaviorEvent event) { 
    System.out.println(tweetType); 
    visibleGTFlag = true; 
}
