mrbdrm wroteyou want to make the user to use the multi upload from a process, right?
if that the case then you can only display the multi-upload form from a referenced BO either by the "use multi-file upload for document attribute" as you have done or by process (as in the Photo Album) and choosing "use custom implementation" .
i am curious how can your users check what they have uploaded or if they uploaded anything? if you don't want to show the reference BO.
Hi,
When the form is presented (parent BO), the users are shown this choices; sorry about wiping out the details, client is a government agency 😃

When they click on any of the buttons, I want the 'File Dialog' to appear and then using the process create them in the BO. Another form is then presented to them to 'accept/review' the files they have uploaded.
If its not possible, then I just have to 'convince' them that they need to see the reference object form
Thanks
