File: classes/process/ProcessDAO.inc.php line 107
By jerico-dev:

The process id is NOT an integer. You could have realized that:
1) By reading the class doc where you'll find a big argument why process id cannot be an integer
2) By reading the process id documentation of all methods which show it to be a string rather than an integer
3) By executing ProcessDAOTest which clearly indicates the error!!!
