Hi,
if it is some more code, it's just not readable very well without
proper formatting and highlighting, more people will enjoy your code
if you use cakebin. :-)
Did you also try to put the code for the second observer in the
complete-function of the first ajax observer? What you can also do
about ajax populated js-code to be executed, is to put in a javascript-
header in the answer, like:
<?php header('Content-type: application/x-javascript'); ?>
