I can't get 'valid_string' validation to work. I have a model with a 'surname' field. In this field - just for testing purposes - I want the user to be able to type only alpha characters, and spaces. The validation is specified in the model like this:

<?php

class Model_Client extends Orm\Model &#123;
 
 protected static $_properties = array(
  'id',
  'created_at',
  'updated_at',
  'given_names' => array(
   'type' => 'string',
   'label' => 'Given Names',
   'validation' => array('trim','strip_tags','required'),
  ),
  'surname' => array(
   'type' => 'string',
   'label' => 'Surname',
   'validation' => array('trim','strip_tags','required', 'valid_string'=>array('alpha','spaces')),
  ),
  'birthdate',
  'birthcountry'
 );
 
 protected static $_observers = array(
  'Orm\Observer_CreatedAt' => array('before_insert'),
  'Orm\Observer_UpdatedAt' => array('before_save'),
  'Orm\Observer_Validation' => array('before_save'),
 );
 
}

Unfortunately, the validation for the surname field *always* fails, as soon as I put anything else in the 'valid_string' array, apart from 'alpha'. It works like this: (1) Using array('alpha') only: works as expected (2) Using array('alpha', *): if anything else is added after 'alpha' (such as 'spaces', or 'dashes'), then it ignores whatever is added afterwards, and validation only works if there are only alpha characters - that is, if I add a space (or a dash), even if I specified that this is be allowed by using 'spaces' (or 'dashes'), then validation fails (3) Using array(*,'alpha'): if anything is added before 'alpha', then validation *always* fails, even if the field contains only alpha characters. Is this a bug, or am I doing something obviously stupid?
