The file is already uploaded with the first form submit....

You may try to save the file object in a session object, but it
will almost surely not work.

You may save the file content and other relevant attributes
(like it name on the client) in a session object.
This will work as long as the file is not two big.

Otherwise, you should write the file to a temporary file
and keep that information in a session object.

Didn't you ask this question only recently?
I seems to me I had answered it already.
