# Breaking: #77391 - DataHandler method protected {#breaking-77391-datahandler-method-protected}

See [forge#77391](https://forge.typo3.org/issues/77391)

## Description {#description}

Method `doesRecordExist_pageLookUp()` of class `DataHandler` has been
changed from public access to protected access and the returned object changed to an
instance of `QueryBuilder`.

## Impact {#impact}

Calling the method will trigger a fatal PHP error.

## Affected Installations {#affected-installations}

Extensions that use method `doesRecordExist_pageLookUp()`. This is very unlikely
since the method is mostly only useful for core internal handling.

## Migration {#migration}

No migration possible, remove the method call.
