FacesMessage is not displayed when being set in an action method with a redirect outcome

Why the code from the first block works and the other one doesn't? It's all about displaying JSF messages

@PostConstruct
public void init() {
    try {
        throw new RuntimeException();
    } catch (RuntimeException e) {
        i18nExceptionHandler.handleException(e);
    }
}

The code above works well - it displays the message.

public String login() {
    try {
       //login actions
    } catch (AuthenticationException e) {
      //this doesn't work
        i18nExceptionHandler.handleException(e);
    }
    return "/pages/loggedin?faces-redirect=true";
}

This code doesn't work - it doesn't display any message and I'm given following error: 

WARNING: There are some unhandled FacesMessages, this means not every FacesMessage had a chance to be rendered.

Why it works like that? Shall I use validator or something else on the login method (and the rest as well)?

Message from the second code block wasn't displayed, because method hasn't got void signature.

You need to include h:messages tag in your jsf page. for example,

<h:messages id="messagesID" globalOnly="true" layout="table" />

If you don't have this in your JSF page, the warning message will arise.
