I thought as much...
If you add the id field:
echo $this->Form->input('id');
...Cake will automatically i) hide it and ii) populate it with the id value of
the record. Make sure the id value is part of the data you are sending to the
form (die(debug($this->data)) will confirm that).
Then when you submit the form, Cake will detect the id value and do an update.
If it is empty, it will do an insert.
The validation will fire in the same way on both. The id value *has* to be
unique, so the validation is doing its job.
