Problem/Description¶

Affects 10.4, 11.x

A language switcher menu based on the MenuProcessor does not generate the correct URL to the default translation of a mount point page which is localized (also the mounted page is localized).

• The problem occurs no matter if I have a language fallback or not.
• pages.mount_pid_ol is set value 1 of the mount point page
• the mount point page and the mounted page are translated (= page translations exists with different slug)

Affected example:¶

1. I have a mount point page with URL slug private-pilotes/how-to-buy which results to a URL slug in the frontend of /en/private-pilotes/how-to-buy/ (according to the language site configuration (see below)).
2. This mount point page is translated. The translated URL slug is privatpiloten/kaufen which results to a URL slug in the frontend of /de/privatpiloten/kaufen/.
3. The language menu works correctly if you are on the default language of the mount point page /en/private-pilotes/how-to-buy/. Both the link to the default language and the german language is correct and as expected.
4. But if I'm on the translated mount point page /de/privatpiloten/kaufen/ the link to the default language of the page is /en/privatpiloten/kaufen/ instead of /en/private-pilotes/how-to-buy/

Environment¶

• TYPO3 10.4.1/10.4.2-dev
  • didn't tested 9.5 because we updated the instance right from TYPO3 8 LTS where this issue did not occur. Therefore I marked this issue as a regression at least for 10 LTS.
• Pagetree with Translation
  • default language (english /en/)
  • second language (german /de/)

Extract from the site configuration (language part)¶

languages:
  -
    title: English
    enabled: true
    languageId: '0'
    base: /en/
    typo3Language: default
    locale: en_CA.UTF-8
    iso-639-1: en
    navigationTitle: English
    hreflang: en-ca
    direction: ltr
    flag: ca
    websiteTitle: ''
  -
    title: Deutsch
    enabled: true
    base: /de/
    typo3Language: de
    locale: de_DE.utf8
    iso-639-1: de
    websiteTitle: ''
    navigationTitle: ''
    hreflang: de-de
    direction: ''
    fallbackType: fallback
    fallbacks: '0'
    flag: de
    languageId: '1'

TypoScript¶

Using the following dataprocessor Configuration

            # Language Navigation
            page.10.dataProcessing.450 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
            page.10.dataProcessing.450 {
                special = language
                special.value = 0,1
                as = LanguageNavigation
                if {
                    isTrue = {$site.nav.language.enable}
                }
            }

Acceptance Criteria¶

A language menu must always link to the correct URL slug of any translation of the actual mount point page no matter which translation of that page is active.
