The GenericObjectValidator dumps all prior calculated validation results, when validating a nested property which has the same class name as the validated object.

Quick example:

class Office {
     * @var string
     * @Flow\Validate(type="StringLength", options={ "minimum"=3, "maximum"=100 })
     * @Flow\Validate(type="NotEmpty")
     * @ORM\Column(length=100)
    protected $title;

     * @var \Doctrine\Common\Collections\Collection<\Company\Project\Domain\Model\OpeningHours>
     * @ORM\OneToMany(mappedBy="office")
    protected $openingHours;


class OpeningHours {
     * @var \Company\Project\Domain\Model\Office
     * @ORM\ManyToOne(inversedBy="openingHours")
    protected $office;


When creating a new Office with a form including one ore more openingHours, all validation errors of properties defined prior to $openingHours are dumped and therefore not displayed as errors. If no other validation error after the $openingHours property occurs, the createAction is executed with no error messages (but not persisted, seems that the validation here works). In the above example an empty $title would pass the validation.

I've tracked it down to the GenericObjectValidator and the ValidatorResolver:
The ValidatorResolver only creates a new baseValidatorConjunction, if none exists for this class name. Otherwise it uses the existing one. Since the GenericObjectValidator's validate() method resets its member $this->result on every call, all results of prior Office properties are deleted as soon as it comes to the validation of the openingHours' $office property.
This does not happen in one of my older projects (with FLOW3 1.1), because there the GenericObjectValidator does not store its results in a member variable, but only calculates it inside the method.
Also it only seems to happen inside collections.
