我有 xhtml 页面，该页面在该数据网格内有数据网格我想通过使用按钮或链接按钮调用方法，我编写如下代码来做到这一点

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"

                        </tr>
                    </thead>
                </table>                                  
            </h:form>                
        </p:layoutUnit>  
    </p:layout>
</h:body>

我调试了代码，但测试方法不会调用。并且没有任何异常或错误。

在不带括号的EL中写入方法名称并添加ajax="false" 

<p:commandButton value="click here" action="#{phonesBean.test}" ajax="false"/>
