Answer 1

Seems to me like the login input in Users\Form\RegisterFilter

$this->add(array(
     'name' => 'login',
     'required' => true,
     'filters' => array(
         array(
             'name' => 'StripTags',
         ),
         'validators' => array(
             array(
                 'name' => 'StringLength',
                 'options' => array(
                     'encoding' => 'UTF-8',
                     'min' => 2,
                     'max' => 20,
                 ),
             ),
         ),
     ),
));

should be defined like this:

$this->add(array(
     'name' => 'login',
     'required' => true,
     'filters' => array(
         array(
             'name' => 'StripTags',
         ),
      ),
      'validators' => array(
          array(
             'name' => 'StringLength',
             'options' => array(
                 'encoding' => 'UTF-8',
                 'min' => 2,
                 'max' => 20,
             ),
         ),
     ),
));
