我有下面的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"/> 我添加了一个如下的faces消息:
@ManagedBean
public class MessageControler {
public void eventAdded(){
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO,"Rezerwacja została dodana",null));
}
}但是,它不会显示在咆哮组件中。这是如何引起的,我如何解决它?

我下面的最小示例可以工作,也许您可以检查commandButton的属性
