Class "legacy" not found

Using Neos & Flow Installation & Deployment
#1

Hi

I tried to upgrade my test system from Neos 4.3 LTS to 5.3 LTS. After updating via Composer it says:

PHP Fatal error:  Uncaught Error: Class 'legacy' not found in /var/www/html/neoscms/Packages/Framework/Neos.Flow/Classes/Core/Booting/Scripts.php:237
Stack trace:

I’ve no idea what “legacy” is - any idea? PHP was updated to 7.4, too.

Thanks for your help,

Great - that workd!

Now I’m 400 lines closer to the end of the Scripts.php:

Do you have a second idea? :wink:

can you do that?

Of course:

I think it has sth. to do with a View Helper I’ve written.

Until now this class uses “TYPO3Fluid\Fluid\ViewHelpers\ForViewHelper” and “TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface”. It defines a function

/**
 * @return void
 */
public function initializeArguments()
{
    parent::initializeArguments();
    $this->registerArgument('sortByTitle', 'boolean', 'Set to true in order to sort by title', false);
}

I was able to change the RenderingContextInterface to Neos\FluidAdaptor\Core\Rendering\RenderingContextInterface. But is there a still a ForViewHelper in the current version? Or isn’t it necessary to update the namespace?

Your issue could be related to a very recently introduced and fixed bug:


Do you run the latest patch-level release?
