<ohadlevy> slukasik: when two_pane is running, we serialize the form data and send it to the server
<ohadlevy> however file uploads cant be serialzed
<ohadlevy> so they are simply ignored

<ohadlevy> slukasik: ok, this is an issue with foreman two-pane, we probably need to offer a generic solution, would you mind opening an issue?

This is currently not affecting Foreman itself, but it affects plug-ins. My plug-in (foreman_openscap) uses two_pane form for file upload. https://isimluk.fedorapeople.org/blog/pics/file_upload.jpg
