My growl doesn't work, I tried like eveyrthing I found so I'm asking here how to make my growl work. My xhtml is really simple registration and login enclosed with ui:include . I'm using PrimeFaces 6.0. It is definitely different from proposed answer since answers from that doesn't work.

<h:inputSecret id="password" validatorMessage="Pole nie moze byc puste"

<h:messages for="password" style="color:red;margin:8px;" /><br/>
<p:commandButton update="growl" actionListener="#{userMB.Register()}"
icon="ui-icon-check">Register</p:commandButton>
</h:form>
<h:panelGroup>
<ui:include src="login.xhtml" />
</h:panelGroup>
</h:body>
</f:view>
</html>
I'm using this to call my growl in userMB.Register()
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Success", "Login success"));
I'm just learning JSF so please be patient with me.
