we set a locale on each page<x-tad-smaller>Met vriendelijke groeten,

loginMBean has session-scope. Our web-app requires login, anonymous is not allowed. The first page (login page) has hardcoded german locale, but user can define his favouritr locale in preferences and after successfull login the loginMBean.user.locale is initialized.

I'm starting out with JSF and I'd appreciate some clarification regarding internationalization:
I'm using a select menu and backing bean to call setLocale() on the current view, this works fine and I can change the locale of the view in question. But when I navigate to another view the locale reverts back to the browser default.
Is this correct behavior?
Do I need to set the locale myself on a per-view basis or should JSF maintain the locale between views?
If this is the case then I guess I need to store the view's local in the session and use this to set the locale for subsequent views. Where and how would be the best way to do this in terms of the JSF lifecycle?
I also have tiles in the mix using MyFaces JspTilesViewHandlerImpl, does this have any implications for how I need to handle internationalization?
Thanks
