I'm going to be doing some tests on this in the next few days, and I think it can be done with a few field layout overrides, and a small change in JCE (which will bein the update tomorrow).
It basically involves changing the "view" value in the url in the media field layout, to view="files" (instead of view="images"), and then a change in the repeatable field front-end layout so that the PDF is rendered as a link.
Just because you're not paranoid doesn't mean everybody isn't out to get you.
Yep yep yep ! tested and validate ! I make an override of the admin template and install the RC4 : Thanks so much ! When it will ready I will post the solution everywhere I see the issue (JCE media fields is in pro version only ?)
I think I have play with too much things : now in my repeatable fields I have a media field but it don't all JCE Media manager when I create some content. How i have broke this ? (I have test with another website : media field in repeat call jce mediamanager)
