I had some form instances go all the way through their workflows, but the form didn’t write data to our database as it should have due to messed up behaviors I put in. Is it possible to map those completed form instances to the new, corrected version of the form and reset the stage so they can be resubmitted?
Make your changes, publish them and map the old instances to the new version.
In the new version make the changes so your workflow works properly AND build a back door for yourself. On form opens if the user name = your name show a hidden button. When the button is clicked use a Connect object to write to your database and submit.
