webform save draft after each field update - ajax error for anonymous user I wanted to save webform's draft after each field's update, and i did it with help of this post: Webform save draft after each field update .

But it is only working for logged in user, if i try it with anonymous i get ajax error 

"An AJAX HTTP request terminated abnormally.
Debugging information follows.
Path: /system/ajax
StatusText: n/a"

Does anybody have any idea why is this happening? thank you ..
The save draft functionality has not yet been committed for webform for anonymous users. 

According to the post you mentioned, @Stefan in his answer claims he added the functioanlity by incorporating my patch from this issue. (We are testing an updated patch which will be posted to the issue cue within the next couple of days.)
