McCLIM, 1.2.8 An application displaying a data structure

(in-package :common-lisp-user) (defpackage "APP" (:use :clim :clim-lisp) (:export "APP-MAIN"))

(define-application-frame superapp () ( ;(current-number :initform nil ;:accessor current-number) ) (:pointer-documentation t) (:panes (app :application :display-time nil :height 400 :width 600) (int :interactor :height 200 :width 600)) (:layouts (default (vertically () app int)))) ; Evaluation aborted on #<UNBOUND-VARIABLE SUPERAPP {100A25ABA3}>.

How this can be or I missed something again.

The variable SUPERAPP is unbound. [Condition of type UNBOUND-VARIABLE]

best, Igor.
