How to set a user defined language in Xpages

In my xpage I need to set a user defined language before the page loads. the language to be set is stored in a document in the database

so I do this in beforePageLoad

var lang = getUserDoc().getItemValueString("Language")
facesContext.getViewRoot().setLocale(new java.util.Locale(lang));
context.reloadPage();

the problem is that if I do not do context.reloadPage the language is not set.

but context.reloadPage gives all kind of other problems when loading the page so I need to find a better way.

is there anyway I can set the language of the page without reloading the page.

This doc suggests using context.setLocale/setLocaleString instead of viewRoot.setLocale. The advantage is that the context locale is used for the rest of the browser session. The context locale will be set as the viewRoot locale when any subsequent viewRoots are loaded, so you don't have to re-set the locale for every page. It does still require a context.reloadPage for the current viewRoot though, so its not exactly what you were asking for.

The doc is: Locale use in XPages: Programmatically setting the locale

Hope I have got it correctly, just extending my answer to Per Henrik's solution here (based on the last comment), for setting the resource bundle correctly probably you can just compute it? Something like this?

<xp:this.resources>
        <xp:bundle var="application">
            <xp:this.src><![CDATA[#{javascript:if(context.getLocale()=="en_US")
return "/application.properties";
else
return "/application_de.properties";}]]></xp:this.src>
        </xp:bundle>
    </xp:this.resources>

I have just used the context variable here, but I am sure that the document variable is accessible too.

Hope this helps.

Setup a phase listener that sets the appropriate locale based on the user's configuration.

See this blog post by Sven Hasselbach for more details: http://hasselba.ch/blog/?p=649

I use this approach in several apps using the following phase listener based on the approach from Sven. The code reads the locale from a user bean:

public class LocalizationSetter implements PhaseListener {

    private static final long serialVersionUID = -1L;

    public void afterPhase(PhaseEvent event) {
    }

    public void beforePhase(PhaseEvent event) {
        FacesContext facesContext = event.getFacesContext();
        UIViewRoot view = facesContext.getViewRoot();
        view.setLocale(User.get().getLocale());
    }

    public PhaseId getPhaseId() {
        return PhaseId.RENDER_RESPONSE;
    }
}

The problem is beforePageLoad runs too late - the components have already been loaded into the component tree with the relevant language.

It may work if you use a ViewHandler, as in Jesse Gallagher's Scaffolding framework on OpenNTF. You would definitely need to identify the language before the call to super.createView() though.

To use beforePageLoad, I think you would subsequently need to iterate through controls and amend the labels etc.
