Since we've updated to 2.7.1 the EntityType with expanded: true does not accept an entity as a default value anymore. A LogicException occurs when the user goes back to edit the entity, where defaultData is added to the builder:

The form's view data is expected to be of type scalar, array or an instance of \ArrayAccess, but is an instance of class Proxies__CG__\AppBundle\Entity\Order\Subject. You can avoid this error by setting the "data_class" option to "Proxies__CG__\AppBundle\Entity\Order\Subject" or by adding a view transformer that transforms an instance of class Proxies__CG__\AppBundle\Entity\Order\Subject to scalar, array or an instance of \ArrayAccess.

$defaultData = array();
if ($order->getSubject() instanceof Subject) {
    $defaultData['subject'] = $order->getSubject();
}

$form = $this->createFormBuilder($defaultData)
    ->add('subject', 'entity', array(
        'class'      => 'AppBundle:Order\Subject',
        'expanded'   => true,
        'property'   => 'name',
    ))
    ->getForm()
;

The exception can be solved in two ways, by setting expanded to false or by defining data_class:

// ...

$form = $this->createFormBuilder($defaultData)
    ->add('subject', 'entity', array(
        'class'      => 'AppBundle:Order\Subject',
        'data_class' => 'AppBundle\Entity\Order\Subject',
        'expanded'   => true,
        'property'   => 'name',
    ))
    ->getForm()
;

Looks like a BC break, think EntityType should resolve the data_class based on the class right?
