[Bese-devel] I'm simply not getting it:

[Friedrich Dominicus]

Ok, if someone else might be interested I had to modify the send code
too:

(in-package :qss.web.ucw)


;; end of cut+paste code 
(defparameter *test-application*
  (make-instance 'cookie-session-application
                 :url-prefix "/ucw/test/"
                 :tal-generator (make-instance 'yaclml:file-system-generator
                                               :cachep t
                                               :root-directories (list *ucw-tal-root*))
                 :www-roots (list (merge-pathnames "./ucw/test/" *ucw-tal-root*))))


;;;(defmethod shared-initialize :after ((window downloader-window) slot-names &rest initargs)
;;;  (declare (ignore slot-names initargs))
;;;  (initialize-container ((example-window.body window))
;;;    (simple-address 'simple-address)))



(defentry-point "index.ucw" (:application *test-application*) ()
  (call 'show-address :address (call 'get-address)))

(defclass address ()
  ((name :accessor name :initarg :name :initform "")
   (email :accessor email :initarg :email :initform "")))

(defcomponent address-manipulator-mixin ()
  ((address :accessor address :initarg :address :backtrack t
            :initform (make-instance 'address))))

(defcomponent show-address (simple-window-component address-manipulator-mixin)
  ())

(defmethod render-on ((res response) (s show-address))
  (<:p "Your address:")
  (<:table
    (<:tr (<:td "Name:") (<:td (<:as-html (name (address s)))))
    (<:tr (<:td "Email:") (<:td (<:as-html (email (address s)))))))

(defcomponent get-address (simple-window-component address-manipulator-mixin)
  ((message :accessor message :initarg :message :initform nil)))

(defmethod render-on ((res response) (g get-address))
  (<:p "Please submit an address:")
  (when (message g)
    (<:p :style "color: #ff0000; font-weight: bold"
      (<:as-html (message g))))
  (<ucw:form :action (print-info g)
    (<:table 
      (<:tr (<:td "Name:") (<:td (<ucw:text :accessor (name (address g)))))
      (<:tr (<:td "Email:") (<:td (<ucw:text :accessor (email (address g)))))
      (<:td (<:td :colspan 2 :align "center"
              (<:input :type "submit"))))))

(defaction print-info ((g get-address))
  (if (and (name (address g))  (string/= "" (name (address g)))
           (email (address g)) (string/= "" (email (address g))))
      (answer (make-instance 'address :name (name (address g)) :email (email (address g))))
      (setf (message g) "Sorry, you must supply both a name and an email.")))


Of course one can simplify the (name or email (adress stuff but it's
needed for getting that stuff running. 

IMHO this would be a good candidate to be included into the examples.
