drupal_add_js() in page template not working
http://drupal.org/node/482542#comment-1666888

page.tpl.php -Theme implementation to display a single Drupal page.
Available variables:
$messages: HTML for status and error messages. Should be displayed prominently.
http://api.drupal.org/api/drupal/modules--system--page.tpl.php

Your drupal_set_message happens when $messages is already set,
so you are not really changing the message but setting the message for the next
page loading when in

http://api.drupal.org/api/function/template_preprocess_page/6

new $message is set with
 $variables['messages']          = $variables['show_messages'] ?
theme('status_messages') : '';

status messages are stored in a $_SESSION['messages']

So if you want to add your message you should change the variable $message.
In this way the result you get should be the same.

For years I was smart. I recommend pleasant, and you may quote me.
