Now I'm more confused than I was. The wider context is INITIALIZE-
INSTANCE :after method for the flash widget:
(defmethod initialize-instance :after ((obj flash) &rest initargs)
(declare (ignore initargs))
(push (lambda ()
(when (and (flash-messages obj)
(not (refresh-request-p))
(not (initial-request-p)))
(setf (flash-old-messages obj) (flash-messages obj))
(setf (flash-messages obj) nil)))
(request-hook :session :pre-action))
(push (lambda ()
(declare (special *on-ajax-complete-scripts*))
(when (and (ajax-request-p)
(flash-old-messages obj))
(if (flash-messages obj)
(send-script
(ps* `(new (*effect.*pulsate ,(dom-id obj)
(create :pulses
3 :duration 0.5)))))
(send-script
(ps* `(new (*effect.*blind-up ,(dom-id obj))))))))
(request-hook :session :post-action))
(push (lambda ()
(declare (special *on-ajax-complete-scripts*))
(when (and (null (flash-messages obj))
(flash-old-messages obj))
(setf (flash-old-messages obj) nil)))
(request-hook :session :post-render)))
The snippet I pasted before is the :post-action hook. If it doesn't
allow ajax requests, then I'm afraid I don't understand what the :post-
action hook is for. In other words, when would it ever be executed?
To me it looks like it would be when it's an ajax request and there
are old-message (which doesn't make sense to me, even if I were
right).

The flash widget gets rendered something like this:
<div class="widget flash" id="1">
<div class="view">...</div>
<script type="text/javascript">// <![CDATA[$('1').show(); // ]]> </
script>
</div>
Chrome complains about this: "Uncaught TypeError: Ojbect [object
HTMLDivElement] has no method 'show'"
