Actually, it appears that I can save from an action handler - but it's a little tricky and probably not the recommended way (calling validate on the Form from the action handler).
form.form.validate()
if (form.form.isValid()) {
form.save(facade);
facade.save();
form.getChild("contentMessages").addMessage(new I18nMessage('saved',
'application'));
}
