javascript - vue-i18n dynamic locale with promise doesn't update -

i testing vue-i18n in order implement future projects. have separate system handle translations, got remote json files. vue-i18n have system fetch locale using promise, explainations here.

i cannot use fetch method because files outside got cross-origin troubles. instead vue-resource, don't know why, when set new set of locale, doesn't update automatically. bescause default lang en, when load en locale file, nothing. have change 2 times config.lang force update.

several things:

• a jsfiddle test > http://jsfiddle.net/t4kdoqj7/3/ uncomment line 19 reproduce fix

• maybe it's due bad using of vue-resource

• i couldn't create vue-i18n tag...

thank !

ok, found hack :

set vue.config.lang = '' before loading anything
