FormBuilder Question

Hi, A quick question that bothers me: When I submit a form and save a new item, I want either that the form displays an empty form or that the newly created id is loaded into the form object. I; enable hidden fields with primary key hide_primary_key = 1 Is set and works fine when I call the page with a specific id but not after a newly saved item, do I have to add the value myself or shouldnt formbuilder do that for me?
