Ok, thanks. After a some fiddling I was able to figure out how to do this
using parenscript (that capitilization is tricky stuff...) to reload the
current page. I'm curious however whether it is possible to call an action.
It seems that to me that <ucw:a :action .., among other things, creates
a URL that I could in theory embed in the page for the javascript
function to call. But maybe this is pointless?

best,

Just in case this is helpful to anybody, this macro (if added to a
component's render method) will cause the page to be reloaded,
triggering another call to the render method.

(defmacro timed-self-refresh (delay-in-ms)
  `(<:script :type "text/javascript"
    (<:as-is
     (js:js
      (defun init-timed-refresh-call ()
	(set-timeout "doTimedRefreshCall()" ,delay-in-ms))
      (defun do-timed-refresh-call ()
	(window.location.reload))
      (setf window.onload init-timed-refresh-call)))))
