Bug #93207

Updated by Simon Schaufelberger over 3 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>
