how to save a collection form in symfony 1.4 - forms

Question

I have created a collection form in symfony 1.4 and Propel 1.5 and everything displays properly but I cannot get the form to save to the database.
The form is used to edit multiple users at once.
I found this question and I implemented the suggestion of extending my collectionForm class with sfFormPropel, but when I do that I run out of memory. I cannot find what is being pulled from the database that would fill up the processes memory.
In my new save function I am not even doing anything.
Any ideas?
class ContactCollectionForm extends sfFormPropel
{
public function getModelName()
{
return 'ContactCollectionForm';
}
public function retrieveSubObject($fieldname, $model)
{
switch($fieldname)
{
default:
break;
}
return array();
}
public function save($con = null)
{
}
public function configure()
{
$user = $this->getOption('user');
$embedded = $this->getOption('embedded');
$custom = $this->getOption('custom');
$contact_list = $this->getOption('contact_list');
$cf = $custom['form'];
if(!array_key_exists(0, $cf['fields']['field']))
$cf['fields']['field'] = array($cf['fields']['field']);
$use_fields = array();
for($i=0;$i<count($contact_list);$i++)
{
foreach($cf['fields']['field'] as $field)
{
if($field['type'] == 'object')
{
// embed object form (ala: PersonData, Coordinate etc...)
$model = $field['model'];
$model_form = $model.'Form';
$sub_object = $contact_list[$i];
$sub_form = new $model_form($sub_object, array('user' => $user, 'embedded' => true, 'custom' => $field['fields']));
$this->embedForm($field['name'], $sub_form);
array_push($use_fields, $field['name']);
} // end field type == object
else
{
// standard form field
$this->setWidget($field['name'], CustomWidgetExtender::createSfWidget($field, $user, $this));
$this->widgetSchema->setLabel($field['name'], $field['label']);
if(trim($field['default']) != '')
$this->setDefault($field['name'], $field['default']);
// add field name to use_fields array
array_push($use_fields, $field['name']);
} // end field type != object
}
}
}
}

I ended up doing a rough hack by processing each form manually rather than trying to shoehorn this type of form into the symfony 1.x form framework.
