Changing language without changing locale in JSF
I currently have a JSF application which sets the locale based on a user's choice of language. He gets a dropdown, and when choosing English, I set the locale to en, etc. This works very nice with number formats as well as with the language strings loaded from my ResourceBundle.
So for en, I get English words and a . as decimal seperator. For fr, I get French and a , as decimal seperator.
However, there is now a requirement that for this website, the number format must always have a , as decimal seperator. So, I was thinking to keep the locale fixed to fr.
Still the user must be able to change his language. So, is it possible in JSF to load a different language without changing the locale?
Seams you need a special solution for formatting, so overwriting the formatters might be the better solution. I think JSF supports replacing the default number format.
Just explicitly specify the locale attribute of the <f:convertNumber> tags which you're using there.
Eg
<f:convertNumber ... locale="fr" />
or something like
<f:convertNumber ... locale="#{app.defaultNumberLocale}" />
It would otherwise indeed default to UIViewRoot#getLocale() , as you're experiencing.
