Enabling javascript_use_double_submit_protection stops the clicked submit button as being set as $form_state['triggering_element'], I have a custom form that's displayed inside of a ctools modal.
https://www.drupal.org/node/1705618 →
Set $conf['javascript_use_double_submit_protection'] as TRUE, go to a form with more than one submit button, in a modal. Clicking the final submit button and the Form API sets the first button on the form as the $form_state['triggering_element'] as $form_state['triggering_element'] is not set.
The form in my test is displayed inside of a Modal, but I can't see how this makes any difference.
With the lib/ $conf['javascript_use_double_submit_protection'] set to FALSE the form submits as expected.

I've found the issue I think, the elements were a submit and cancel button, I wrapped them in a action section https://api.drupal.org/api/drupal/developer%21topics%21forms_api_referen... and it now seems to work. Closing
