Faces notifications not working

Question

I am having a strange issue with the Faces messages.

Sometimes, the <p:growl>, <p:messages> display correctly the notification after executing some method. But there are specific JSF pages where no notification is shown.

For example:

public String create() {
    try {
        getFacade().create(current);
        JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("NotaCreated"));
        return prepareCreate();
    } catch (Exception e) {
        JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
        return null;
    }
}

The method is called in

<h:commandLink action="#{notaController.create}" value="#{bundle.CreateNotaSaveLink}"/>

And it does not show the notification. But for other entities as well as for other operations the messages are displayed correctly. This happens also in other functions, where I need feedback and it is not shown as expected.

I've been searching around and read this post and tried some of the suggested solutions, including setting the ajax=false attribute in commandButtons and commandLinks or using the scripts posted, but none of that worked for me, so I ask this question hoping that someone can help me.

Do I have to configure something to make it work correctly? I need this to get fixed by tomorrow and I don't know what else to do.

Update:

These are the JsfUtil methods:

public static void addSuccessMessage(String msg) {
    FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
    FacesContext.getCurrentInstance().addMessage("successInfo", facesMsg);
}
public static void addErrorMessage(Exception ex, String defaultMsg) {
    String msg = ex.getLocalizedMessage();
    if (msg != null && msg.length() > 0) {
        addErrorMessage(msg);
    } else {
        addErrorMessage(defaultMsg);
    }
}

This is the Create.xhtml

Your question is missing anything that could be used to help troubleshoot your issue. Where is the view? What's `JSFUtil` and is it working properly? — kolossus, Aug 03 '14 at 16:06
@JaqenH'ghar I have added the methods for messaging. I don't know any other code example to give because all controllers have the same create() method and for some of them it works but for this and others it does not. — Carlos Andres, Aug 03 '14 at 16:49
@kolossus I have added the code for the create view. As I said before, JsfUtil method work for some methods, but not for others. In any method where I call the JsfUtil.addSuccessMessage(message) sometimes the message is displayed and sometimes it doesn't — Carlos Andres, Aug 03 '14 at 16:54
Thanks for your colaboration, I checked my code and found that the problem was only when the return strings had ?faces-redirect=true. I removed that and it worked just fine. But the problem is that I need the redirected link as a requirement. How can I deal with that without having this issue? — Carlos Andres, Aug 05 '14 at 06:25

I had the same problem. The faces message wasn't rendering it was being lost. I tried this code and it worked.

FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
FacesContext context = FacesContext.getCurrentInstance();
context.getExternalContext().getFlash().setKeepMessages(true);
context.addMessage("successInfo", facesMsg);

I hope it works.

I did tried that before posting this. I was getting a warning console message about the messages, don't remember, but found out that the problem is when you put in the return strings ?faces-redirect=true – Carlos Andres Aug 05 '14 at 06:20
@Carlos Andres Read the accepted answer in this link [link]http://stackoverflow.com/questions/13685633/how-to-show-faces-message-in-the-redirected-page BalusC talks about a bug in messages when the page is redirected. Maybe it's your case. – pamps Aug 05 '14 at 11:47
