The config for the sonata_admin_phpcr_admin.document_tree contained a mapping for a class which has been removed (SimpleCmsBundle\Document\Page). This class has been replaced with 
Symfony\Cmf\Bundle\SimpleCmsBundle\Doctrine\Phpcr\Page and this mapping is required in order for Sonata Admin to display and allow editing of the default documents created by the SimpleCmsBundle in the PHPCR.
