I am working on requirement where I need to pre populate half of the sections with multiple fields and attachments in adaptive form other form data which has already submitted. Since the data model /XSD is similar for both of the forms I am thinking to capture data xml of previous submission and remove elements which are not present in new form. I am able to populate data but facing issue with attachments. I am curious to know if there is any way to retrieve all attachments from previous submission with help of prefill service. Any suggestion to implement this would be really helpful and highly appreciated.
