Go back to reading ;-) because it is easier to throw 2 different custom
exceptions NotEmptyCategoryException (has some products) and
NotLeafCategoryException (has some subcategories) from beforeDelete() and
then either react differently for them or (in controller):
try {
...
} catch (CakeException $e) {
$this->Session->setFlash($e->getMessage());
}
