Migrating to php 8.2 - how to solve deprecated dynamics properties

Try to add:

PHP Code:

use AllowDynamicProperties; 


But the best way is to define the properties you use.
Because dynamic properties are deprecated.

Use AllowDynamicProperties still does not work (or maybe I did not place it where it should for it to work. 

But I now understand what you meant by "define properties".  

PHP Code:

protected $viewData = [];
protected $session = []; 


solved my issue.

Thanks

After that, I got $_SESSION errors, do I need to update system folder something like change session.name to session.id?
