I just found the persistData(), thought it doesn't appear to be used
anywhere. I did some more hacking and added Zend_Session_Namespace into the
mix. I'll check out the Helper proposal to see if I'm missing anything.
In case anyone wanted to see my current, semi-working example, here ya go:
<?php
require_once 'ApplicationController.php';
require_once 'Zend/Form.php';
require_once 'Zend/Session/Namespace.php';
class IndexController extends ApplicationController
{
public function siteInformationAction()
{
$subform = $this->_getForm()->getSubForm('site_information');
if ($this->getRequest()->isPost() &&
$subform->isValid($this->getRequest()->getPost())) {
$subform->persistData();
return $this->getHelper('redirector')->gotoRoute(
array(
'action' => 'personalInformation'
)
);
}
$this->view->form = $subform;
$this->render('form');
}
public function personalInformationAction()
{
$subform = $this->_getForm()->getSubForm('personal_information');
if ($this->getRequest()->isPost() &&
$subform->isValid($this->getRequest()->getPost())) {
$subform->persistData();
$this->_getForm()->process();
exit;
}
$this->view->form = $subform;
$this->render('form');
}
private function _getForm()
{
return new Site_Form_Create();
}
}

parent::__construct(array(

Site_Form_Create_PersonalInformation()
)

}
public function process()
{
foreach ($this->getSubForms() as $subform) {
var_dump($subform->getValues());
}
}
}
