I think it would be the beez kneez to ship ctools with a sample module that shows how to use the AWESOME POWER of the ajax and modal functionalities. I saw Roger present this in NYC, and wrote such a module on the plane to NOLA. I'm open to suggestions of other things we should show off how to do, but here's a first attempt.

This could also be merged with the existing sample module rather than starting as it's own.

Thanks for this piece of code Josh!

It helped me to prepare my own demo modules to the session of Drupal camp.

I discovered a little bug in your code that was difficult to track, but I found finally the reason:

This is a piece of code from ctools.module file:

function ctools_js_load($js) {
  if ($js == 'ajax') {
    return TRUE;
  }
  return 0;
}

It makes that the argument that you pass to the callback function converts to TRUE or 0

In your code you have:

function ctools_ajax_sample_hello($js = NULL) {
  $output = '<h1>Hello World</h1>'; 
  if ($js == 'ajax') {

When should be directly if ($js). yeah! that easy

That condition is stopping your code from working when javascript disabled.

This conversion of "ajax" to TRUE only happens if you use in the hook menu the argument %ctools_js

If you use any other name, it will not happen.

So I avoided to use %ctools_js to do it more "cross-drupal-compatible", because it seems Drupal 7 AJAX framework won't have these conversions.

Here the slides and demo code I prepared, hope it helps someone:
