p：growl不显示全局面部消息

标签： jsf primefaces growl

我有以下命令按钮和咆哮组件：

<p:commandButton id="reservationAdd" actionListener=" {reservationBean.addReservation()}" value="Dodaj" oncomplete="PF('wdlgAddReservation').hide();"  update=":frm" action="#{linkedTimelinesController.createTimeline()}"> 
    <f:ajax execute="reservationAdd" onevent="click" listener="#{messageControler.eventAdded()}"  render="dynamic"/>
</p:commandButton>

<p:growl id="msj" autoUpdate="true"/>

我添加了一条面孔消息，如下所示：

@ManagedBean
public class MessageControler {

    public void eventAdded(){  
      FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO,"Rezerwacja została dodana",null));  
    }
}

但是，它不会出现在growl组件中。这是怎么造成的，我该如何解决？

我的以下最小示例有效，您可能会检查commandButton

的属性

@ManagedBean
public class Page {

    public void triggerEvent() {
        FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Test!", null));
    }
