Switch Language User-specific [message #1552825]

Hi all!

I translated my RAP Application in different languages. My problem is switching the language user-specific.

When i try
Locale.setDefault(Locale.ENGLISH);
Messages.reloadMessages();

The language switches for all users.

I also tried
RWT.getUISession().setLocale(Locale.ENGLISH);
but this had no effect.

Please can anyone give me a hint?

Hi,
using RWT.getUISession().setLocale(Locale.ENGLISH) or
RWT.setLocale(Locale.ENGLISH) is correct. See our demo at [1] and it's
source [2].

Thanks for quick reply, but unfortunately this has no effect in my application. Sad

Any other ideas?

HI,
what is your default system locale? Do you have messages_en.properties file?
Regards,
Ivan

Yes, I have the messages_de.properties and the messages.properties as default in English.

I checked out this site:
http://eclipse.org/rap/developers-guide/devguide.php?topic=internationalization.html&version=2.0

Now it's the issue that changing language is possible, but when another user changes language, sometimes (!) the language for the other user changes, too.
CRAZY!

My default system language is german.

Another question:
Is it necessary using reset NLS Suffixes like
Field nlSuffixesField = NLS.class.getDeclaredField("nlSuffixes"); //$NON-NLS-1$
nlSuffixesField.setAccessible(true);
nlSuffixesField.set(NLS.class, null);

And reloading Messages with
NLS.initializeMessages(BUNDLE_NAME, Messages.class);

???

In fact the RWT.setLocale()-Methode has no effect in my Application.

If i test

ClientInfo clientInfo = RWT.getClient().getService(ClientInfo.class );
System.out.println(clientInfo.getLocale());
RWT.setLocale(Locale.ENGLISH);
clientInfo = RWT.getClient().getService( ClientInfo.class );
System.out.println(clientInfo.getLocale());

Output:
de_DE
de_DE

nothing has changed in the configuration.

Hi,
ClientInfo service always returns the locale set in the browser. If you
change the RWT locale programmatically, use RWT.getLocale() to obtain it
back. If locale is not changed programmatically, RWT.getLocale will
return the client browser locale (from ClientInfo service).
HTH,
Ivan

Think i got an approach.
The locale of the current uisession reverts its state to german.

Do you have an idea why and when this happens?
I switch the perspective after switching the language.

Maybe anyone has the same problem, so here the solution:

I thought Locale.ENGLISH would trigger using the messages.properties.
But the right way was Locale.US. And there has to be a messages_en.properties.
So now the right language files are used.
