Ctools wizard back button with #action I'm trying to build a multi-step form with Ctools that will submit to another website upon completion (a hosted payment page). On the last form page, I have set the #action property in the form array to allow it to submit to this other website. My issue however is that this seems to affect the Back button behavior on this form page and directs me to the website I specified in #action when clicked, which is obviously not desired. 

Are there additional settings I can tweak to make the Back button behave correctly with the #action property set?
You could drop the #action, then add some curl() code to your #submit callback function for the final step.

Trickier, sure, but it'll work without messing up the form caching for Drupal.
