TYPO3 Core

I am using addToAllTCAtypes to extend an field with a Palette like this:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes(
    'tx_myext_entities',
    'header;;pl_header;;',
    '',
    'replace:header'
);

The types of the tx_myext_entities table looks like this:

return array(
    'ctrl' => array(
        'title' => 'tx_myext_entities',
    ),
    'interface' => array(
        'showRecordFieldList' => 'header'
    ),
    'columns' => array(
        'header' => array (
            'exclude' => 1,
            'label' => 'Header',
            'config' => array (
                'type' => 'input',
                'size' => '255',
            )
        )
    ),
    'types' => array(
        '0' => array('showitem' => 'header')
    ),
    'palettes' => array (
        '1' => array('showitem' => ''),
    )
);

With TYPO3 6.2.11 and before i get the folowing result after the addToAllTCAtypes call:

return array(
    'ctrl' => array(
        'title' => 'tx_myext_entities',
    ),
    'interface' => array(
        'showRecordFieldList' => 'header'
    ),
    'columns' => array(
        'header' => array (
            'exclude' => 1,
            'label' => 'Header',
            'config' => array (
                'type' => 'input',
                'size' => '255',
            )
        )
    ),
    'types' => array(
        '0' => array('showitem' => 'header;;pl_header;;')
    ),
    'palettes' => array (
        '1' => array('showitem' => ''),
    )
);

Since TYPO3 6.2.12 the header field was not replaced anymore.
The remaining calls to add the palette and te new columns i have omitted the sake of clarity.

I have found out, that the removeDuplicatesForInsertion method is the cause. This Method removes all duplicates, but ignores the insert position "replace", so a replace of an field is not possible.

This error exists since the fix in #65480 wit the following commit:

[BUGFIX] Compare field names without configuration

With patch https://review.typo3.org/34019/ the function
ExtensionManagementUtility::removeDuplicatesForInsertion was rewritten.
But the rewrite fails for fields with additional configuration and
returns wrong field information.

Resolves: #65480
