Thanks for explanation...
But I am unable to do what you explain because I try to make a kind of
virtual table to form submission... So I need the "virtual table name" I
pass by request.args(0) to access some dict that I build to make my virtual
table to work...
May I request "request.args(0)" form "my_form_processing" if the only thing
"my_form_processing" get is the form?
It works once, but I think it not working every time. I mean I get my own
"my_form_processing" function to works with request.args(0), but it not
seems to work anymore after restart web2py (local dev with rocket built-in
server).
Thanks
Richard
