How to update sfUserProfile after the completion of a separate module? postSave() not working

Question

I have a registration form that includes sfRegistration and sfProfile, which after completion, get's redirected to another form - to determine the user's corporation and is a seperate module. The sfProfile includes a field from the corporation module... the corporate_id. But since the corporate_id is not part of the profile, it does not get included at registration time. Here's the question, after completion of the corporation module, what is the best way to update the user's profile with the corporate_id of the newly completed corporation module? I tried this:

public function postSave()
{
$corpId = $this->form->getId();
$logged_user_id = sfContext::getInstance()->getUser()->getId();
Doctrine_Query::create()
->update('sf_guard_user_profile p')
->set('p.corporate_id', $corpId)
->where('p.user_id' == $logged_user_id )
->execute();
}

placed into the action of the company module, but it is not updating the profile with the company_id.

Suggestions?

UPDATE - per request, here is the information requested: (my >>lib>form>>doctrine>>CorporationForm.class.php is empty... I was trying my functions in the actions class... which may be the issue). Just to clarify, I just need to update the user's profile with the newly created corporate_id after the user completes the corporation module.
And my schema:

Don't forget the ->save();

    public function setId() 
  {
        $user_id = $this->getUser()->getGuardUser()->getId();
        $corp_id = 1;
        $user_profile = Doctrine_Core::getTable('sfGuardUserProfile')->findOneByUserId($user_id);
        $user_profile->setCorporateId($corp_id)->save();
   }

  protected function processForm(sfWebRequest $request, sfForm $form)
  {            
    $form->bind($request->getParameter($form->getName()), $request->getFiles($form->getName()));
    if ($form->isValid())
    {
        self::setId();        
        $corporation = $form->save();    
        $this->redirect('dashboard/index');      
    }
  }

In your form:

public function  doUpdateObject($values)
  {

   parent::doUpdateObject($values);
   $this->getObject()->setCorporateId(your value);

}

For example //apps/frontend/yourmodule/action.class.php

protected function processForm(sfWebRequest $request, sfForm $form)
    {
    $form->bind($request->getParameter($form->getName()), $request->getFiles($form->getName()));
    if ($form->isValid())
    {

       $corporation = $form->save();
       $user_id=$this->getUser()->getGuardUser()->getId();
       $profile = Doctrine_Core::getTable('sfGuardUserProfile')->findOneByUserId($user_id);
       $profile->setCorporateId('your value');
