"Allow users to save a draft" set, but no "Save draft" button appears on Webform

Your form has to have at least 2 pages for the button to show up I believe.

@quicksketch do you know the reason why it is limited to webforms with more than one page?

I guess it will make sense for single-page forms too, as for long forms or forms that need a lot of research.

I'm not 100% sure, perhaps that's the way the original patch was written? Let's move this to a feature request.

I haven't tested this extensively, but it seems to do the trick.

This patch works for me. Thanks.

This has been fixed as part of #834526: Keep user on the same page when saving as Draft. The save as draft button always appears now, even on one-page forms.

Actually, still unresolved. Using Drupal 6.20 and Webform 3.5

Had one page form and no save draft button was appearing. Made it in two pages and the button appeared.

It's fixed in later versions of Webform. Upgrade to 3.9.
