Question

Change the default language for anonymous user

2

Hello, I have two languages in my project Arabic and English. Is there a way to change the default language for anonymous users to Arabic? I want when anyone hits the URL to display it in Arabic. Note: changing the default language to Arabic is not solving the problem.

As your role-based homepage for anonymous users, I would select a microflow that does something like this:

After that you can navigate to whatever page is currently your homepage. If it doesn't directly show the page in arabic, you may have to force a reload in the flow.

Hey folks! Sorry for necroing the topic, but I think I found a solution (after googling the problem and finding this topic).

The key is to have a Microflow that runs for anonymous users (eg. I placed one as a data source for a Data view in my page template, so it runs for everyone); you can retrieve the System.User object with the [System.Session_User = $currentSession] XPath constraint, then add a decision that checks if the user is anonymous and has their language set to something other then the "forced default" language of your choice (Hungarian / hu_HU in my example, for OP's case it should be ar_something):

$currentUser/IsAnonymous

and $currentUser/System.User_Language/System.Language/Code != 'hu_HU'

...if that is true, you can add an activity to retrieve a single System.Language object from the database using an Xpath constraint along the lines of [( Code = 'hu_HU' )] and subsequently add a Change object activity which updates the previously retrieved System.User object with the retrieved System.Language. I added commit & refresh in client for good measure, I'm not sure if the latter is necessary/ideal, I'm still pretty novice in Mendix.

UPDATE: I switched to using a Nanoflow which calls the Microflow if language is not set to the "forced" one, then calls the Atlas_Core/LanguageSelector/ReloadWithState JavaScript action to quickly reload. It flashes a bit, so not perfect, but I think it's acceptable.
