Bug #93207
Updated by Simon Schaufelberger almost 4 years ago
I noticed that handleErrors is called twice in Build/Sources/TypeScript/backend/Resources/Public/TypeScript/AjaxDataHandler.ts.
Once in AjaxDataHandler->initialize and again in AjaxDataHandler->process.
One of both should be removed. I believe removing the one in initialize makes more sense as the one in process will also get called when deleting a record.
How to reproduce:
Put these lines in \TYPO3\CMS\Backend\Controller\SimpleDataHandlerController::processAjaxRequest after "$this->tce->printLogErrorMessages();" to force an error flash message:
<pre><code class="php">
$flashMessageService->getMessageQueueByIdentifier()->addMessage(GeneralUtility::makeInstance(
\TYPO3\CMS\Core\Messaging\FlashMessage::class,
'Duplicate error message!',
'Duplicate error message title',
\TYPO3\CMS\Core\Messaging\FlashMessage::ERROR
));
</code></pre>
