PHP 7.2.5 Uncaught Error: Class 'Dompdf\Frame\FrameTreeList' not found

[torsten...@tradeshift.com]

Hi all,

I upgraded to PHP 7.2.5 from 7.1.1 and dompdf was running into errors not finding classes.

I downloaded dompdf latest version from git as well as in a release version but the same issue appeared when executing the code. I basically reduced everything to the example code given by dompdf for showing "Hello World" but it it does not work.

Full Error with "Hello World":

Fatal error: Uncaught Error: Class 'Dompdf\Frame\FrameTreeList' not found in /srv/www/htdocs/vhosts/app.com/dompdf/src/Frame/FrameTree.php:131 Stack trace: #0 /srv/www/htdocs/vhosts/app.com/dompdf/src/Css/Stylesheet.php(1040): Dompdf\Frame\FrameTree->get_frames() #1 /srv/www/htdocs/vhosts/app.com/dompdf/src/Dompdf.php(721): Dompdf\Css\Stylesheet->apply_styles(Object(Dompdf\Frame\FrameTree)) #2 /srv/www/htdocs/vhosts/app.com/order_print.php(104): Dompdf\Dompdf->render() #3 {main} thrown in /srv/www/htdocs/vhosts/app.com/dompdf/src/Frame/FrameTree.php on line 131

My current Code:

require_once 'dompdf/autoload.inc.php';

$html = 'Hello World';

//use Dompdf\Dompdf as Dompdf;   // Already commented out as it was described inside a forum 

$dompdf = new Dompdf\Dompdf();    // Changed due to a forum description

$dompdf->load_html($html);

$dompdf->set_paper("A4", 'portrait'); 

$dompdf->render();

$dompdf->stream("order.pdf", array("Attachment" => 0));

Former code with the guthub downlod has all require() included; rest was the same.

require_once 'dompdf/lib/html5lib/Parser.php';

require_once 'dompdf/lib/php-font-lib/src/FontLib/Autoloader.php';

require_once 'dompdf/lib/php-svg-lib/src/autoload.php';

require_once 'dompdf/src/Autoloader.php';

Dompdf\Autoloader::register();

Any idea what is going wrong here ?

Thanks

Torsten
