Question

JSF Locale exception

Answer 1

A:

Well, you need to set the default value. Either

Locale currentLocale = FacesContext.getCurrentContext()
           .getApplication().getDefaultLocale();

or

@PostConstruct
public void init() {
    currentLocale = FacesContext.getCurrentContext()
           .getApplication().getDefaultLocale();
}

He already did it in the constructor. The problem is that the constructor doesn't look like a constructor due to the poor naming conventions. The other problem is that it returns the server side locale which may return null if not explicitly set/configured.

ah, right.. well, he said he has set the default locale in faces-config.. but let's see it.

Answer 2

A:

The error says that the Locale is null while it may not be null. You need to preinitialize it with ExternalContext#getRequestLocale() which will return the client side locale, not with the Application#getDefaultLocale() which would return the server side locale which may be null if not explicitly configured.

So, update your code with

public changeLang() {
    this.currentLocale = FacesContext.getCurrentInstance().getExternalContext().getRequestLocale();
}

That said, it's recommend to adhere the Sun Java Naming Conventions. Classnames ought to start with uppercase, else it would confuse everyone because it look like methods. Rename changeLang to ChangeLang.

Well , I uppercased the first letter of the class name, then changed the constructor but I still get the same error.
