Using forceLanguage does not load language automatically

[elpeq]

Hello,

tested in angular-translate 2.9

forceLanguage doesn't work if StaticFilesLoader is used:
$translateProvider.useStaticFilesLoader

@elpeq Please provide always a working demo with your issue.

I've made a demo, but cannot see any problem with this: http://plnkr.co/edit/iiBTCvK3t2qwUeTZiamd?p=preview

@elpeq Is a language failing to load, and then you're using forceLanguage? I handled the rejection from the static file loader and that let me continue.

return $translateStaticFilesLoader({ prefix: 'languages/', key: options.key, suffix: '.json' })['catch'](function () { return {}; })

Hello @knalli
I've adapted your demo and added a 3 language pt_PT that shows, that the force language doesn't work.

Alright: the language will be not loaded automatically.

Forcing a language is now working in version 2.11.0 but it produces errors when trying to switch to another language afterwards:

angular.js:13236 TypeError: Cannot read property 'key' of undefined
    at angular-translate.js:2216
    at processQueue (angular.js:15552)
    at angular.js:15568
    ...

You should be able to reproduce the issue if you click in any language button on the updated demo Plunk (see console for stack trace):

FYI, angular-translate determines my preferred language as French, which is correct.

In fact after some more testing, it looks like forcing a translation only works properly when using the translate pipe. Take a look to the improved demo again:

• When using the translate-force directives, it fails radomly (probably due to the promise mechanism behind the scene).
• Note that I had to comment the $translateProvider.determinePreferredLanguage() call as it seems to conflict with $translateProvider.fallbackLanguage() (see fallbackLanguage() invocation changes breaks useLocalStorage #1075) and breaks completely translate-force.

Unless there is something wrong in the demo, this issue should be reopened again.

We don't reopen.. the workflow is always a new issue. => #1471
