colSpan not working in the backend view

[patrickklosedev]

I have the following configuration in the file tt_content.php:

According to an example of this extension, this should lead to having the first row span the two columns that follow.
However, this is the result in the backend:

Is this a bug or did I used "colSpan" wrongly?

TYPO3 12?
"Layout-Mode"

but "Language-Comparison-Mode"

this is same as core backend_layout rendering behaviour.

Yes, Typo3 V12.
And even in Layout Mode, it doesn't work.

When I check the source code, the defined colspan is not used.
By changing this value directly in the source code, it works (temporary):

[achimfritz]

this is my source-code (with EXT:container_example, https://github.com/b13/container-example/blob/master/Configuration/TCA/Overrides/tt_content.php#L11)

ah i see ..., you have to write "colspan" instead of "colSpan" in your configuration

[patrickklosedev]

Unfortunately, this doesn't work either...
I already have this tried before.

I will try out your code example and get back to you.

Same issue in v12.

Same problem here with TYPO3 11 and latest EXT:container. PHP 7.4 or 8.2 doesn't matter.

It works in column view, but not in language view.

[engelart-development]

Typo3 12.4.21
PHP 8.2
Container 2.3.6

\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\B13\Container\Tca\Registry::class)->configureContainer(
(
new \B13\Container\Tca\ContainerConfiguration(
'2cols-container', // CType
'2 Spalten', // label
'Container Element für 2 Spalten', // description
[
[
['name' => 'linke Spalte', 'colPos' => 10],
['name' => 'rechte Spalte', 'colPos' => 20],
],
[
['name' => 'Erweiterung', 'colPos' => 30, 'colspan' => 2]
]
] // grid configuration
)

We have examined the problem in detail.
The reason why the colspan set in the TCA is not used could be found in sysext/backend/Classes/View/BackendLayout/Grid/GridColumn.php:

    public function getColSpan(): int
    {
        if ($this->context->getDrawingConfiguration()->getLanguageMode()) {
            return 1;
        }
        return $this->colSpan;
    }

In languageView the TCA values are ignored. Crazy...

Thanks for digging into it. So next step is to open a core issue?
