Associations ONLY work with $scaffold - cakephp

Question

New to Cake, and trying to set up model associations. I'm creating an execution planner, to be used by multiple teams, aka 'groups' where the base unit of a plan is an 'event'. Each event is owned by one team, but it can have many supporting teams.
When I use $scaffold in the controllers, the model associations work as expected and when adding a new event I get a select box with all the groups to select who owns an event. However, when I bake the controller using console, the select box for group_id is blank. I've included the baked add() code from the controller, and from the baked add view. I also tried debug($this) in add.ctp, and found that the list of groups is indeed being passed to the view. I'm thus mostly confused about why it works with $scaffold, but not otherwise.
Any advice or pointers in the right direction would be greatly appreciated.
Tables:
CREATE TABLE IF NOT EXISTS `events` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`group_id` int(5) NOT NULL COMMENT 'Group that owns event',
`version` int(5) NOT NULL,
`type` varchar(5) NOT NULL,
`stime` time NOT NULL,
`etime` time NOT NULL,
`description` text NOT NULL,
`comment` text NOT NULL,
PRIMARY KEY (`id`)
);
CREATE TABLE IF NOT EXISTS `events_groups` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`event_id` int(5) NOT NULL,
`group_id` int(5) NOT NULL,
PRIMARY KEY (`id`)
) ;
CREATE TABLE IF NOT EXISTS `groups` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`code` varchar(4) NOT NULL,
`name` varchar(25) NOT NULL,
`liveversion` int(4) NOT NULL,
`lastupdated` date NOT NULL,
PRIMARY KEY (`id`)
);
Models:
Event:
public $belongsTo = array(
'Prigroup' => array(
'className' => 'Group',
'foreignKey' => 'group_id',
)
);
public $hasAndBelongsToMany = array(
'Secgroup' => array(
'className' => 'Group',
'joinTable' => 'events_groups',
'foreignKey' => 'event_id',
'associationForeignKey' => 'group_id',
)
);
Group:
public $hasMany = array(
'Prievent' => array(
'className' => 'Event',
'foreignKey' => 'group_id',
)
);
public $hasAndBelongsToMany = array(
'Secevent' => array(
'className' => 'Event',
'joinTable' => 'events_groups',
'foreignKey' => 'group_id',
'associationForeignKey' => 'event_id',
)
);
EventsController Snippet:
public function add() {
if ($this->request->is('post')) {
$this->Event->create();
if ($this->Event->save($this->request->data)) {
$this->Session->setFlash(__('The event has been saved'));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The event could not be saved. Please, try again.'));
}
}
$prigroups = $this->Event->Prigroup->find('list');
$secgroups = $this->Event->Secgroup->find('list');
$this->set(compact('prigroups', 'secgroups'));
}
Add view:
<?php echo $this->Form->create('Event'); ?>
<fieldset>
<legend><?php echo __('Add Event'); ?></legend>
<?php
echo $this->Form->input('group_id');
echo $this->Form->input('version');
echo $this->Form->input('type');
echo $this->Form->input('stime');
echo $this->Form->input('etime');
echo $this->Form->input('description');
echo $this->Form->input('comment');
echo $this->Form->input('Secgroup');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
Add HTML Output
<div class="input select"><label for="EventGroupId">Group</label><select name="data[Event][group_id]" id="EventGroupId">
</select></div>

Can u try something for me please? Rename the $prigroups variable to "groups" and pass it to the view. See if this is working. Otherwise use this one with your old code:
echo $this->Form->input(
'group_id',
array(
'options' => $prigroups
)
);
I also recommend you to use camel case for all those PriGroups and SecGroups. Those are two words in english so camel case advisable.
