Hi J,
Of course you were here too :)
I solved the issue by using SQLFORM.factory to generate the form for those
pages where there was a dictionary variable. I've edited the code so that I
think I got it working properly.
I save the form.vars of each page to session.page_nro and at the end (four
phases) I add them all to a one dictionary to add it to database:
db.campaign.insert(**db_data).
It seems to work okay.
