Easyadminbundle: Deprecation messages in EasyAdmin 1.x

[fabienlem]

Hello,

I'm just wondering if you plan to fix deprecation messages in EasyAdmin 1.x in order to allow Symfony 4.3 upgrade.

I get two errors:

A tree builder without a root node is deprecated since Symfony 4.2 and will not be supported anymore in 5.0.

The "EasyCorp\Bundle\EasyAdminBundle\Controller\AdminController" class extends "Symfony\Bundle\FrameworkBundle\Controller\Controller" that is deprecated since Symfony 4.2, use "Symfony\Bundle\FrameworkBundle\Controller\AbstractController" instead.

Thank you a lot for your feedback.

Fabien

I plan to release the last version of 1.x branch very soon and stop developing it. So, if these deprecations can be solved easily without breaking any existing app, we'll merge them. Any volunteers to create that PR? Thanks.

I've fixed the Treebuilder deprecation in #2936 ... but I'm afraid we can't fix the other deprecation because the 1.x branch works with Symfony 2.x, 3.x and 4.x ... so we can't use AbstractController.

I think this shouldn't be a problem because the AbstractController deprecation was introduced in 4.2, so you can upgrade to 4.3 and 4.4. You won't be able to upgrade to 5.0 ... but this doesn't matter because EasyAdmin 1.x won't be compatible with Symfony 5.x or higher.

So, I'm closing this as fixed, but if someone has a clever idea to solve this too, we can reopen. Thanks!
