# Breaking: #67402 - Extbase AbstractDomainObject initializeObject {#breaking-67402-1668719172}

See [forge#67402](https://forge.typo3.org/issues/67402)

## Description {#description}

Method `initializeObject()` has been removed from `TYPO3CMSExtbaseDomainObjectAbstractDomainObject`.

## Impact {#impact}

Possible fatal error in Extbase if objects are thawed from persistence.

## Affected Installations {#affected-installations}

Domain objects extending AbstractDomainObject and calling `parent::initializeObject()`.
This is relatively unlikely since the default implementation of `initializeObject()` is empty.

## Migration {#migration}

Remove calls to `parent::initializeObject()` from own `initializeObject()` implementations.
