[openstack-dev] [Horizon] Modal form without redirect

If you look at the code in the post()[1] method of the base workflow view you'll note that a response to a successful workflow POST is always a redirect[2] (caveat for when it's specifically adding data back to a field, which isn't relevant here).

The reason for this is that in general when you POST via a standard browser request you want to send back a redirect so that reloading the page, etc. behave correctly and don't potentially result in double-POSTs.

If you're submitting the workflow via a regular HTTP from submit POST then I'd say redirecting is correct; you simply want to redirect to the current page. If you're doing this via AJAX then you'll want to add some new code to otherwise signal a successful response (both to the code and to the user) and to take action accordingly.

Hope that helps,
