TYPO3 Core

Context

I combine two fields via TCA Slug ['city', 'street']. TYPO3 builds the slug correctly to e.g. "cologne/streetname". This is also displayed in the backend in the slug field.

        'slug' => [
            'exclude' => true,
            'label' => 'URL Segment',
            'config' => [
                'type' => 'slug',
                'generatorOptions' => [
                    'fields' => ['city', 'street'],
                    'replacements' => [
                        '/' => '',
                        '&' => ''
                    ],
                ],
                'fallbackCharacter' => '-',
                'eval' => 'uniqueInPid',
            ],
        ],

Problem

If i call a list action which call this slug via f:link.page I get this error message:

Parameter "tx_ayacoopoi_poi__poi" for route "tx_ayacoopoi_poi_0" must match "[^/]++" ("cologne/streetname" given) to generate a corresponding URL.

I have not defined a field separator in the TCA config and so a slash is used by the code => https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/core/Classes/DataHandling/SlugHelper.php#L185

Symfony routing is in strict mode and so the slash isn't allowed.
