[support] AHAH 403 error

[Doug]

Just re-reading through the AHAH section of "Pro Drupal Development".
The only AHAH attribute that comes close to actually specifying a
client-side javascript function to be invoked is "method", which must take
a value of iether "append", "before","prepend" or "replace" and then
the javascript jquery itself is (from misc/ahah.js) 

if (this.method == 'replace') {
  wrapper.empty().append(new_content);
} else {
  wrapper[this.method](new_content);
}

I looked at this once before and decided that AHAH seemed to be only useful 
for animating form elements themselves, or modifying the "wrapper" around 
the form element (but its quite possible I was wrong about that - maybe 
there is a black-art to generating special "new_content" JSON in your 
MENU_CALLBACK?).

My AJAX use case was for for getting events and injecting them into a
javascript (jquery) calendar (not drupal related) embedded in a 
drupal menu "page callback". I ignored AHAH altogether and just used
jquery's AJAX function directly - activated by an onclick attribute 
attached to a handrolled button (to avoid the every-button-is-submit
bug).

Cheers
Doug
