Correct, as well as an accessor for retrieving the form:

public function getBugForm()
{
if (null === $this->_bugForm) {
$this->_bugForm = new Module_Form_Bug();
}
return $this->_bugForm;
}

The basic technique is like this:

public function save(array $data)
{
$validator = $this->getBugForm();
if (!$validator->isValid($data)) {
return false;
}
$values = $validator->getValues();

// ...
}

However, you could also do this:

public function save(Module_Form_Bug $data)
{
$values = $data->getValues();

// ...
}

which would assume you've validated first, and simply be using the
filter chain capabilities of the form.
