When a Nintex form is edited, I need to keep the pre-edit SharePoint list item and create a new SharePoint list item for the edited form on submission - I want to perform a 'NewForm' submit from 'EditForm'. I'm a Nintex Forms newbie and not sure how this can be achieved, so any help would be much appreciated.
I haven't played a lot with Form variables but if you load all the existing values into form variables on Form load and display them in new input fields on the form, you should be able to save these new values to new variables and perform a Create new item in the workflow.
I will try this as well and let you know.
It's possible to do this but can you achieve what you need by using SharePoint's versioning?
I can't use SharePoint versioning because a workflow runs on form creation/edit that includes updates to some list item fields.
