[postmodern-devel] How to use auto-id?

Hi, I'm not sure how to use auto-id in my deftable statement. I have something like this: (deftable cities () ((id :type integer :initarg :id :accessor id) (name :type string :initarg :name :accessor name)) (:class-name city) (:auto-id t)) However, if I use something like (select-dao 'city) To get the list of all cities, I get this error: The assertion (= (LENGTH POSTMODERN::QUERY-FIELDS) POSTMODERN::N-FIELDS) failed. What am I doing wrong? TIA, Vamsee.
