TYPO3 Core

Steps to reproduce the problem¶

• Install EXT:styleguide
• Inside styleguide/Configuration/TCA/tx_styleguide_inline_mnsymmetric_mm.php change the TCA for the fields hotelid and branchid to type group:

        'hotelid' => [
            'label' => 'hotelid',
            'config' => [
                'type' => 'group',
                'internal_type' => 'db',
                'allowed' => 'tx_styleguide_inline_mnsymmetric',
                'minitems' => 1,
                'maxitems' => 1,
                'size' => 1,
            ]
        ],
        'branchid' => [
            'label' => 'branchid',
            'config' => [
                'type' => 'group',
                'internal_type' => 'db',
                'allowed' => 'tx_styleguide_inline_mnsymmetric',
                'minitems' => 1,
                'maxitems' => 1,
                'size' => 1,
            ]
        ],

• Clear the TYPO3 cache
• Create two records of table `tx_styleguide_inline_mnsymmetric` inside the TYPO3 backend
• Edit the second record, click on "Create new" in field branches
• A new IRRE shows up, inside the IRRE in the field branchid select the first created record
• Save your changes

Actual results¶

• In Record 1 and Record 2 inside the IRRE the field branchid is displayed

Expected results¶

• In Record 1 (in this case it's the symmetric side) hotelid should be displayed
• In Record 2 (in this case it's the foreign side) branchid should be displayed

Additional notes¶

• Per default EXT:styleguide uses select fields inside styleguide/Configuration/TCA/tx_styleguide_inline_mnsymmetric_mm.php
• This is working like expected, the bug occures only with type group

After some debugging i noticed, that the condition inside typo3/sysext/backend/Classes/Form/FormDataProvider/TcaInlineIsOnSymmetricSide.php->addData() is not working for type group.

I tested with:

• TYPO3 10.4.10, EXT:styleguide 10.0.4
• TYPO3 current master, EXT:styleguide 11.0.1
