CakePHP deep (multiple related models) validation? - associations

Question

I have a model structure that is:
Organization belongsTo Address belongsTo CountryCode
So, Organization has foreign keys: mailing_address_id and physical_address_id
Address has foreign key: country_code_id
In the Organization model, relationship is defined as:
public $belongsTo = array(
'MailingAddress' => array('className'=>'Address', 'foreignKey'=>'mailing_address_id')
, 'PhysicalAddress' => array('className'=>'Address', 'foreignKey'=>'physical_address_id')
);
This appears to be working great - validation is functioning properly, etc.
In the Address model, relationship is defined as:
public $belongsTo = array(
'CountryCode' => array('className'=>'CountryCode', 'foreignKey'=>'country_code_id')
);
In my OrganizationsController, in a function to create a new organization, I'm testing validation using this code:
if($this->Organization->saveAll(
$data, array('validate'=>'only')
)) {
// Validates
$this->DBG('Org validated.');
} else {
// does not validate
$this->DBG('Org NOT NOT NOT validated.'.print_r($this->Organization->invalidFields(),true));
}
The $data array looks like this going into validation.
2015-06-08 21:03:38 Debug: Array
(
[Organization] => Array
(
[name] => Test Organization
)
[MailingAddress] => Array
(
[line1] => 100 Main Street
[line2] =>
[city] => Houston
[state] => TX
[postal_code] => 77002
[CountryCode] => Array
(
[name] => United St
)
)
[PhysicalAddress] => Array
(
[line1] => 100 Main Street
[line2] =>
[city] => Houston
[state] => TX
[postal_code] => 77002
[CountryCode] => Array
(
[name] => United St
)
)
)
The country code SHOULD NOT validate with the rules I have set in the CountryCode model:
public $validate = array(
'name' => array(
'nonemptyRule' => array(
'rule' => 'notEmpty'
,'required' => 'create'
,'message' => 'Must be provided.'
)
,'dupeRule' => array(
'rule' => array('isUnique', array('name','code'), false)
,'message' => 'Duplicate'
)
)
,'code' => array(
'rule' => 'notEmpty'
,'required' => 'create'
,'message' => 'Must be provided.'
)
);
However, validation PASSES on Organization->saveAll.
Also, if I attempt to access the CountryCode model from the OrganizationController, it's not loaded.
As in:
$this->Organization->MailingAddress->CountryCode->invalidate('name','Invalid!');
In that case, I get an error that CountryCode is null.
Any ideas why CountryCode wouldn't be validating or loaded?
Is validation supposed to work two steps away?

It turns out, there IS a deep option when validating (and saving). It's documented here with the saveAll options:
http://book.cakephp.org/2.0/en/models/saving-your-data.html
So, the validation block in the question works perfectly well if you include the deep option like so:
if($this->Organization->saveAll(
$data, array('validate'=>'only', 'deep'=>true)
)) {
// Validates
$this->DBG('Org validated.');
} else {
// does not validate
$this->DBG('Org NOT NOT NOT validated.'.print_r($this->Organization->invalidFields(),true));
}
