If you have updated to the latest version of trunk (18.104.22.16860) and you use something like
$this->model->recursive = 2; $this->model->findAll();
in your code, it is possible that you have a bug in your application as the findAll() does no longer return all the data you expect. I think, the reason for that behavior is that there was a bug in the recursive handling of CakePHP which is fixed now. Fixing my application was easy: I had to increase the recursive value by 1:
$this->model->recursive = 3; $this->model->findAll();
In this case it paid off that I have tests, otherwise I wouldn’t have noticed that problem in my application that fast.
