I have the requirement to pre-fill values on a form when creating a new item(document/form).
The values will be pulled in from a repeating section template based on a key topic/title exisitng in the template. Workflow runs when the form is saved but this is too late. User need the specified fields to be pre-filled in. It is a long form with many repeating sections. Any help/ideas will be greatly appreciated. system is onPrem 2013
Unfortunately what you are trying to acheive is not possible with Nintex Forms. There are lookup controls but there is no way to parse the xml of the repeating section in the form.
