We are building out an application that will be made available through the forms portal.
Is there any way possible that we can send the application back to the applicant for corrections?
No, a public user can only submit public message start events and cannot be involved in any user tasks. If the application needs to be amended, you could send an email back to the user letting them know what was wrong and that they need to fill out the form again.
To make it easier on the user, you could include their submitted values in the URL back to the form so it's prepopulated with their submission information. To make it more robust, you could have WF save all their submitted values to a database with some GUID, then send them a URL with that GUID so when they open up the starting form, the GUID would trigger a lookup and get all their data back on the new form.
Thanks Jared, that is what I assumed but I promised my team I would check and find out.
Your two additional options sound like potential wins we could deploy. Specifically the first example. Is there any documentation you can provide me on how to include their submitted values in the URL back to the form so it's already pre-populated?
This will work well for a limited number of responses, but can be overloaded since URLs have a character limit. Also keep in mind that you'd be putting the user's submitted data in the URL which isn't particularly secure. A more secure approach is to store their data in a database with a GUID, send the GUID as a URL parameter, and then have the form do a lookup to retrieve that values when they load it back up.
