Hi devs,

Trying to address http://jira.xwiki.org/browse/XWIKI-6228 I noticed today a big 
problem with the way translations work.

$xwiki.getDocument('Main.Welcome').getTranslatedDocument('fr').plainTitle

No matter what language I request, the title will always be displayed in English. This is 
caused by the fact that for all translations, the title is actually 
$msg.get("xe.dashboard.wiki.welcome"), and $msg uses the context language, not 
the document language. This means that getting the right title of the document is almost 
impossible.

Given that we've separated the displayers from the oldcore and the main 
rendering engine, we could change their behavior so that document translations 
would work better. Whenever displaying some information from a document, we 
should temporarily change the context language to be the same as the document's 
language, if any. This would be a backwards-incompatible change, but IMO it's a 
change for the better.

Can you give examples of things that will break for our users?

I can't think of any. IMO using a l10n bundle in a language other than that of the document is wrong, but perhaps some users will be baffled to see search results in a "different" language. For example, using a search query that returns all the different versions of the Main.Welcome message, currently baffles users by the fact that the same document appears many times; will it baffle them to suddenly see results in Swedish, Lithuanian, Russian, Chinese and so on, in a wiki that they though was only in their language?

That particular problem will be addressed in the future, though, since by default we'll just show results in the current language.
