File Validator strange behavior

I am using "Validation\Validator\File" to validate an uploaded file:

            new Validation\Validator\File([
                'maxSize' => $this->getValidationConfig()->maxSize,
                'allowedTypes' => $this->getValidationConfig()->allowedTypes,
                'maxResolution' => $this->getValidationConfig()->maxResolution,
                'messageSize' => ':field exceeds ' . DigitalUnitsConverterUtil::bytesToMb(
                    $this->getValidationConfig()->maxSize) . ' Mb',
                'allowEmpty' => false

The value being validated is:

        'image' => $this->image,

And $this->image is being set inside method "onConstruct()":

    public function onConstruct()
        $this->image = $this->request->getUploadedFiles('image')[0];

But, always the validator says that value is empty. I used xdebug to check, but the value is not empty and contains "Phalcon\Http\Request\File". What is going wrong ?


I think the error is in fields names, as per file.zep code, it checks for "name, size, type, ...etc", but the "Phalcon\Http\Request\File" does not contain this fields. The value should be set again to be validate, like:

    $valueToBeValidated = [
        'name' => $this->image->getName().
        'type' => $this->image->getType(),
