我开始学习JSF和primeface。我有一个xhtml页面和一个Dialog但是CommandButton中的actionListener在我更新时不起作用。 请帮我。 这是我的xhtml文件的内容

答案 0 :(得分：0)
您的命令按钮应如下所示：
<p:commandButton value="Ajouter" update=":main:listTab,:main:messages " icon="fa fa-check"
actionListener="#{continentBean.ajouterContinent()}"
oncomplete="PF('continentAdd').hide();" />
您不需要ajax =＆＃34; true＆＃34;，这是默认设置，最重要的是，当您打算进行ajax调用时，您必须使用actionListener而不是{{1} }（用于标准的同步POST请求）。
