Does CakePHP convention require primary key to be auto-incrementing?

Dear CakePHP gurus,

I am using cakephp scaffolding feature to build a basic CRUD application. I have a table which gives problem when adding new record. I discover that the reason is that the primary key is not auto-incremented. May I know whether this is part of CakePHP convention that primary key has to be auto-incremented?

Other tables with primary keys which are auto-incremented do not give me problems.
