Hello,

I'm trying out the method to change language at runtime as described here: http://tomsondev.bestsolution.at/2014/10/13/effeciently-dealing-with-translations-in-an-e4-app-with-the-help-of-java8/.

First of all, it works really great, very nice job !

But I do have one question : can I handle the labels of Application.e4xmi with this method ?

I thought at least the part labels should be manageable with

@Inject MPart part ;
//...
registry.register(part::setLabel, registry::PartNameKey) ;

But this doesn't seem to work. And of course, menus etc. couldn't be done at all like this.

If I use the standard OSGi-resource bundle, I lose the benefit of the at-runtime language change.

Any tips on how to proceed ... ?

In theory this should work what I don't understand is why you loose
runtime locale change when you use OSGi-Resource Bundle. If you
application model is internalized it should simply work.

If you provide a demo application I can run, I can try to see what's
wrong and what needs to be fixed.

I've joined a little demo in attachment : the only things to translate are the name of the pane & the menu items. The resource bundles are found at the default localion, OSGI-INF/I10n/.

I wonder if the problem is not simply the way I try to set the new Locale (code in handlers.SwitchLanguage :

"context.set(TranslationService.LOCALE, param);" works for the translation of source code, perhaps not for the translation of Application.e4xmi ?

I also tried (without succes either) :

System.setProperty("osgi.nl", param) ;
Locale.setDefault(Locale.forLanguageTag(param));

Attachment: TestLocale.zip

Well to change the locale you need to use the ILocaleChangeService

@Inject
ILocaleChangeService lcs;

//...

lcs.changeApplicationLocale(...)

Much better now, all the menu items are automatically translated, and the part labels in the demo work fine too.

There is, however, one thing that still not works: the part labels in case the parts are shared elements, and are referenced to by placeholders in perspectives. Is this something I should report or is it more likely I'm doing something wrong ... ?

Yes - sounds like a bug in the renderers.
