Why am I getting an error with this form choice set to multiple. This is coming directly off of Symfonys website. All I changed was the variable name.
$builder->add('genre', 'choice', array( 'choices' => array( 'x' => 'x', 'y' => 'y', 'z' => 'z', ), 'multiple' => true, ));
This is the error:
Unable to transform value for property path "genre": Expected an array.
Here is my entity class for this variable:
/** * @var string * * @ORM\Column(name="genre", type="text", nullable=true) */ private $genre;
