[BUG] setLanguage from useSessionContext is not working

[karladler]

Problem description and current behaviour

Using setLanguage the languageId is not updated.

Context

• calling setLanguage() fires indeed a http request with the correct language id in payload:
  • {"languageId":"LANGUAGE_ID"}
• The refreshContext() is correctly fetching the context again

  • But in the context response is still the old language id

    "context": { ... "languageIdChain": ["OLD_lANGUAGE_ID"] ... }

Expected Behavior

Changing the language should update languageId in the component.

Steps To Reproduce

Minimal code for reproduction, anywhere in a Nuxt project:

<script setup lang="ts">
    const { languageId, setLanguage } = useSessionContext();
</script>

<template>
     {{languageId}}

      <button @click="setLanguage({ id: 'ENGLISH_ID' })">
            Change to English
        </button>
        <button @click="setLanguage({ id: 'GERMAN_ID' })">
            Change to German
        </button>
</template>

Anything else?

I am not sure if this is an composables problem or an actual core error.

Hi Karl Adler (@karladler) thank you for creating the issue.

The main problem is the naming - languageId returns the default salesChannel language. That's why you see the same ID even if you change the language.

I added currentLanguageId - for better understanding
