Subject

Why do we need to support symfony 2.2 ? why not just change this method here
https://github.com/sonata-project/SonataDoctrinePhpcrAdminBundle/blob/1.x/Form/Listener/CollectionOrderListener.php#L59
to the new createPropertyAccessor()?

Steps to reproduce

Go to Sonata Admin section / Slideshow Block and create a new block
In the Items Elements section, click Add, nothing works, the URL returns an exception

Expected results

Normal workflow of Cmf Slideshow Block Bundle

Actual results

nothing appears and the ajax request returns an exception which is

Attempted to call an undefined method named "getPropertyAccessor" of class "Symfony\Component\PropertyAccess\PropertyAccess".
Did you mean to call "createPropertyAccessor"?
   500 Internal Server Error - UndefinedMethodException

[dbu]

uh. for the rest, we require symfony 2.3, but there is a dependency for property accessor 2.2 in composer.json... this makes little sense, even 2.3 is end of live. can you please do a pull request where you change dependency and code to the 2.3 variant (and maybe check if there are other similar places? do that against the 1.x branch, we can release it as a patch version - there is no BC break, just dropping a too old version from composer.json.

Ok, I will do this along with my other pending PRs on sonata-project

[stale]

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
