CakePHP 2.2 saveAll multiple models validation

Question

I'm trying to validate multiple models on saveAll. The validations in the first model are being triggered but when it comes to the related model, nothing seems to be happening. I even tried to check if the beforeValidate() and beforeSave() methods are being called by putting an exit; in them but the code continues to execute as normal.

ContactDetails Model:

<?php
class ContactDetails extends ContactAppModel {  
    public $actsAs = array("MapValidate");
    public $hasMany = array(
        'ProjectLocation' => array(
            'className'     => 'ProjectLocation',
            'foreignKey'    => 'project_id'
        )
    );

    public $validate = array(
        'name' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Contact name is required'
            )
        ),
        'address1' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Contact address 1 is required'
            )
        ),
        'email' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Contact email is required'
            ),
            'email' => array(
                'rule' => array('email'),
                'message' => 'Contact email format is not valid'
            )
        )
    );
}

ProjectLocation Model:

<?php
class ProjectLocation extends ContactAppModel {
    public $actsAs = array("MapValidate");
    public $belongsTo = array(
        "ContactDetails" => array(
            "className" => "ContactDetails",
            "foreignKey" => "project_id"
        );
    );

    public $validate = array(
        'lat' => array(
           'checkLocation' => array(
                'rule'    => array('checkMap', 'lat'),
                'message' => 'One or more positions on the map are invalid.'
            )
        )
    );  
}

This is the $this->request->data that I'm trying to save:

Array
(
    [ContactDetails] => Array
        (
            [id] => 1
            [name] => PreeoStudios
            [address1] => 4, Stivala Street
            [address2] => Mosta, MST 3205
            [address3] => Malta
            [telephone] => 34562737
            [email] => [email protected]
            [fax] => N/A
            [skype] => N/A
        )

    [ProjectLocation] => Array
        (
            [0] => Array
                (
                    [lat] => 35.886277456343024
                    [lon] => 14.428907312499973
                )

            [1] => Array
                (
                    [lat] => 35.886277456343024
                    [lon] => 14.528907312499973
                )

        )

)

The saveAll call:

$this->ContactDetails->saveAll($this->request->data, array('validate' => 'first'))

EDIT

I also tried to remove the validation rules from the associated model and put an exit in the beforeSave function... the code just keeps executing

<?php
class ProjectLocation extends ContactAppModel {
    public $actsAs = array("MapValidate");
    public $belongsTo = array(
        "ContactDetails" => array(
            "className" => "ContactDetails",
            "foreignKey" => "project_id"
        );
    );

    public function beforeSave(){
        exit;
    }

    public $validate = array(

    );  
}

Answer 1

Try adding the option deep:

$this->ContactDetails->saveAll($this->request->data, array('validate' => 'first', 'deep' => true))
