[GBBopen-developer] Possible mistake in tutorial.pdf

[Chun Tian (binghe)]

Hi, GBBopen Developer

I'm reading tutorial.pdf, page 54, the definition of function  
INITIALIZATIONS:

(defun initializations (event-name &key &allow-other-keys)
   (declare (ignore event-name))
   ;; Clean up any previous run:
   (delete-blackboard-repository)
   ;; Make a new known-world space instance:
   (make-space-instance
    '(known-world)
    :dimensions (dimensions-of 'location)
    :allowed-unit-classes 'location))

I think the :ALLOWED-UNIT-CLASSES keyword should take a list of  
symbol, not just one symbol, or I cannot run (START-CONTROL-SHELL)  
correctly:

(defun initializations (event-name &key &allow-other-keys)
   (declare (ignore event-name))
   ;; Clean up any previous run:
   (delete-blackboard-repository)
   ;; Make a new known-world space instance:
   (make-space-instance
    '(known-world)
    :dimensions (dimensions-of 'location)
    :allowed-unit-classes '(location)))

Am I right?
