Hi all !
I would like to set the user locale as a thread local variable from an
interceptor (based on the user account) and get this value from a custom
LocalePicker.
But it seems that the LocalePicker.getLocale() is called before
interceptors.
Is there some way to configurer the execution order to have muy interceptor
called before the LocalePicker ?
No. But you can do the following:
1. Create a custom ActionBeanContext that retreives the user account
information based on either request.getUserPrincipal(), other request
data, or the session. Put your variable in a request attribute.
Configure the StripesFilter to use this class directly or put it in an
extension package.
2. Create a custom LocalePicker (subclass the DefaultLocalePicker for
example). It get's the request, so you can access your variable to
determine the locale to use.
Configuration is analogous to point 1.

Late answer, but I faced the same issue with a new application.
The Locale is in dabatabse on the user, but I can't load the user as
Stripersist is not initialized yet when MyLocalePicker is called...
FosPat,
I imagine you meant "Late question". Correct? If so, let me offer a
3rd option on at least how we handle this which may or may not be useful
to you or offer you other ideas when a DB is involved.
Until the user logs in for the 1st time we need to determine the users
locale in a way that does not involve the DB. We use UrlRewriteFilter
for many of our requirements involving domains but one nice feature it
has is to write a class that does anything. In our PreProcessFilter
class we go through a series of checks to determine the users locale
i.e. we start with is there a locale cookie, otherwise check the accept
langs on the request, etc... and once its determined its added on the
request and a cookie is created if it wasn't present. We then have a
custom locale picker that simply looks for and pulls this locale from
the request and provides it to Stripes.
Once the user logs or is logged in their preferred or profile locale
gets set as a locale cookie (unless it already exists and matches the
existing locale cookie) and everything else behaves the same. Also if
they ever clear their cookies the above process will reset it from their
profile.
