这是我的backingBean

        }  

    }
    public void supprimerContinent(){
        addMessage("System Error", "Please try again later.");
    }

    public void addMessage(String summary, String detail) {

    }


}

Answer 1

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）。

p：commandButton没有在p：对话框中触发
