Answer 1

You have to add the growl to the update attribute of your commandButton, aswell. Like this:

<p:growl id="idgrowl"/>
...
<p:commandButton value="Save" update="growl" action="#{etudeBean.save()}" />

And in your managed bean add the FacesMessage the following way:

FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO,"Etude"+etude.getDesignation()+"modifiée avec succes","Mot de passe ancienne non valide: ");
FacesContext.getCurrentInstance().addMessage(null,msg);

This should work.
