I don't understand the end of the code where you bind() your form to an
input. Is it just to package an example? If not, I don't understand what
you're trying to do. If you want to change the default values, then use
setDefaults(). The bind() method is to be used only when the client
submit data.

The setLabels() method can set labels for fields in the current widget
schema. You must be able to change the label of the general field and
also change the labels of the fields inside the general schema.
$schema->setLabel('general', 'General Things');
If you want to change the labels for the embedded schema, use:
$schema['general']->setLabels(array(
'name' => 'Name',
'notes' => 'Notes',
));

Just remove everything i18n related and you're done. As of symfony 1.1.0
beta4, the translations are managed automatically for you. The
sfFactoryConfigHandler registers the i18n objects as the default
translation callable for your forms:
sfWidgetFormSchemaFormatter::setTranslationCallable(array($this->factories['i18n'],
'__'));

The best way to embed a form into another is to use the embedForm()
method In your ClientForm configure() method, add:
$this->embedForm('address', new AddressForm());
symfony will automatically embed the address widgets and validators in
the current form. It will also change the address name format
accordingly. And now, just move all the labels, and helps stuff related
to the address from ClientForm to the AddressForm to simplify things a bit.
And everything will work automatically, and recursively.

Here is your form rewritten will some improvements:
<?php
class AddressForm extends sfForm
{
public function configure()
{
$this->setWidgets(array(...));
$this->setValidators(array(...));
$this->setLabels(...);
$this->setHelps(...);
}
}
class ClientGeneralForm extends sfForm
{
public function configure()
{
$this->setWidgets(array(
'name' => new sfWidgetFormInput(),
'notes' => new sfWidgetFormTextarea(),
));
$this->widgetSchema->setLabels(array('name' => 'Name', 'notes' =>
'Notes'));
$this->widgetSchema->setHelps(array(
'name' => 'Enter a name for this client.',
'notes' => 'Enter any additional notes or profile information.',
));
}
}
class ClientForm extends sfForm
{
protected $client;
public function __construct(Client $client, $options = array(),
$CSRFSecret = null)
{
$this->client = $client;
parent::__construct(array(), $options, $CSRFSecret);
}
public function configure()
{
$this->setWidgetSchema(array(
'id' => new sfWidgetFormInputHidden(),
));
$this->widgetSchema->setNameFormat('client[%s]');
$this->setValidators(array(
'name' => new sfValidatorString(array('min_length' => 2,
'max_length' => 63)),
));
$this->embedForm('address', new AddressForm());
$this->embedForm('general', new ClientGeneralForm());
$this->setDefaults(array(
'id' => $this->client->id,
'general' => array(
'name' => $this->client->name,
'notes' => $this->client->notes,
),
));
}
}
Now, when displaying the form, the id field will have a name of
client[id] and the notes field will have a name of client[general][notes].
