Sonata Admin - boolean field type, label not displayed

Question

I'm creating a Sonata Admin page for an Entity (generated with Symfony CLI).

In this Entity I have 3 textfields and 1 checkbox(boolean). Everthing is well generated except the checkbox. The checkbox is strangly located and there is no label.

In the configureFormFields I defined the checkbox field as it:

->add("online",null, array('required' => false, "label" => "My label"))

And on the Entity I have:

 /**
 * @ORM\Column(name="online", type="boolean", nullable=false)
 */
 private $online;

Here is a screenshot:

Is it a known problem? Have you got any solution?

Answer 1

OK I found the solution:

I was using Symfony 2.6.* when I changed to Symfony 2.3 problem was fixed!

So I look in SonataAdmin GitHub issue to found this working solution: https://github.com/sonata-project/SonataAdminBundle/issues/2630

At the end I am in Symfony 2.6 with checkbox label.
