I have been wanting the ability to be able to dynamically change a user's
locale. Here is the use case:
User is using a computer owned by someone else and cannot modify
settings.
User wishes to view psmls in his or her own language (if possible) which
is different from owner of computer.
User should be able to switch locale to see psmls in own language as
well as internationalized messages.
Currently, Jetspeed determines the locale by examining the header
information sent by the browser. If a user wishes to view a page in a
certain languge/country without specifying the exact language and country on
the url, it cannot happen.
Looking at the code, Jetspeed tends to continually reset the locale during
session validation and the locating of templates. I would propose the
attached patch to allow for the ability to change the locale dynamically.
Once that patch is applied, an action could be written that could change the
locale without it getting reset by Jetspeed.
There is another message in regards to this topic:
http://www.mail-archive.com/jetspeed-dev%40jakarta.apache.org/msg04921.html
This deals with the ability to change the l10n messages dynamically. I do
not believe that the code attached in the message relies on the locale
object stored in the user's temporary storage though. Perhaps this could be
the basis of the action to change the user's locale for viewing different
psmls, as well as the l10n messages.
Does anyone have any thoughts?
Thanks,
Jeremy Ford
