I have the same problem.
After submitting form I get Notice: Undefined index: #ajax in function ajax_form_callback() (string 379 at file includes/ajax.inc).

Finally, I got it to work .. I was getting the "Notice: Undefined index: #ajax in ajax_form_callback()" error for ages and I googled google to find a solution to my problem but in vain!

I have the below situation:

  1. Drupal 7.20
  2. Entity reference prepopulate - to populate a dropdown entity reference field
  3. Two Entity reference fields (checkboxes) with views filtering enabled (entity reference display)
  4. Hook form alter to add ajax functionality and more

The issue: I wasn't able to bind the two entity reference fields together using #ajax. The $form_state['triggering_element']['#ajax'] array wasn't available in ajax.inc ajax_form_callback.

The reason: I was restricting access to the scope of code that adds the #ajax to the desired field.I was checking a $_GET parameter for the entity reference prepopulated field at the beginning of the form alter. This causes the ajax request (path: system/ajax) to not access the code and not rebuild the form again with #ajax property. So check that the ajax request when executed it sees the ajax code again. This is my understanding so far cause when I added the below it worked perfectly:

if (isset($form_state['input']['my_ajax_field_name']) || isset($_GET['my_get_parameter_name'])) {

Though I think the best practice is to set the path in the #ajax array to something like 'system/ajax?nid=nid' which I'm still not being able to do.. cause the ? char gets wrong. Any ideas?
