Breaking: #97787 - AbstractMessage->getSeverity() returns ContextualFeedbackSeverity

See forge#97787


The class \TYPO3\CMS\Core\Messaging\AbstractMessage and the extended class \TYPO3\CMS\Core\Messaging\FlashMessage both have a method getSeverity() to return a flash message's severity. The return type of the method is changed to return an instance of \TYPO3\CMS\Core\Type\ContextualFeedbackSeverity.

As this method isn't supposed to be used publicly, it is declared internal now.


Relying on the return type of \TYPO3\CMS\Core\Messaging\AbstractMessage->getSeverity() being int will throw a TypeError exception.

There is no negative impact in the following cases: * Using the severity enum in Fluid for direct rendering * Using the severity enum in json_encode() In these cases, the enum's value is automatically used.

Affected installations

All extensions using \TYPO3\CMS\Core\Messaging\AbstractMessage->getSeverity() in PHP are affected, if the integer type is expected.


If the integer type of \TYPO3\CMS\Core\Messaging\AbstractMessage->getSeverity() is expected, use the value property of the ContextualFeedbackSeverity enum:

$flashMessage = new \TYPO3\CMS\Core\Messaging\FlashMessage('This is a message');
$severityAsInt = $flashMessage->getSeverity()->value;

The same applies to Fluid template, where the severity is used within another structure, e.g. as an array key:

<div class="x" class="{severityClassMapping.{status.severity.value}}">
    <!-- stuff happens here -->
