# Breaking: #83241 - Extbase: Removed custom functionality for DataMapper->getPlainValue {#breaking-83241}

See [forge#83241](https://forge.typo3.org/issues/83241)

## Description {#description}

Extbase's DataMapper allowed for wrapping string values in custom user functions via custom parameters.
This was primarily placed in DataMapper for allowing TYPO3's legacy DBAL / `$GLOBALS['TYPO3_DB']`.

The functionality is now removed, as the Generic Backend is handled via Doctrine DBAL.

## Impact {#impact}

Calling `DataMapper->getPlainValue()` with the third or fourth parameter set will have no effect anymore.

## Affected Installations {#affected-installations}

In an VERY unlikely case of using a custom Persistence Backend within Extbase in an extension, some
transformations will not work as expected anymore.

## Migration {#migration}

Use the transformations outside the DataMapper, if still necessary.
