just handle it outside web2py. Building a form with SQLFORM changing the
widget at your will is not going to work.
it's like you asking for a checkbox field but using a textarea to do
it.....it doesn't make any sense...
Maybe we'll have in the future an upload mapped to a list:string (sounds
about right) and something that processes that accordingly, but out of the
box right now you just can't use SQLFORM facilities for this expecting it
to work.....
AFAIK cgi.FieldStorage can't process out of the box HTML5's multiple input
files.
