我正在尝试使用p:selectOneRadio>进行Ajax事件，而我正在

以下是更多代码

<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方法

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

Answer 1

试试这个

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

Answer 2

您可以尝试使用事件“ ValueChangeEvent”，请看我的示例：

public void renderUploadPanel(ValueChangeEvent event) {
    String selecteValues = event.getNewValue().toString();
    visibleGTFlag = true;
}

p：ajax抛出方法找不到异常，用p：selectOneRadio
