[cells-devel] Celtk: Error "Slot CTK::PACKING is missing from ..."

[Frank Goenninger]

Hi all:

Another Celtk challenge for me:

The slot CTK::PACKING is missing from the object
SENDREQUEST-PUBLISH-RB-GROUP of class
#<STANDARD-CLASS CTK::MENU-RADIO-GROUP> during operation SLOT-VALUE
    [Condition of type PROGRAM-ERROR]

is resulting from this piece of code:

(mk-row ()
   (mk-stack ()
      (mk-menu-radio-group
          :id :sendrequest-publish-rb-group
          :selection (c-in nil)
         :kids (c? (the-kids
                             (mk-menu-entry-radiobutton
				         :label "Request/Reply"
					 :value :request/reply)
				      (mk-menu-entry-radiobutton
				         :label "Publish"
					 :value :publish)
				      ))))
    (mk-stack ()
       (mk-row ()
	  (mk-label :text "Timeout: "
			    :width 10)
	  (mk-entry :id :timeout-entry
			    :width 6)
	  (mk-label :text "s")))


menu-radio-group inherits from menu-entry which inherits from tk-object.

I can't locate the source of this error ...

Thanks for any hints!

Best,
    Frank
