to back up what robert is saying in your function definition you are
declaring $id=null. if your function is not getting an $id passed to
it
that would cause an insert not an update.
in short you should make sure you are passing an id and also put a
conditional check on $id such as:
//if we find an item with this id
//you could use read() instead of find
if($this->find('first', array('conditions'=>array('Model.id'=>$id))))
{
$this->Model->id = $id;
}
else {
//failed to get model id
//now this acts like an add form
//or die
}
