In fact, this seems to be a bug not so much with setting default values,
but with form validation.
I am doing:
if form.process().accepted:
and somehow, in this validation process, if the string fields are ['a',
'b'] (the string 'a' filled in the first entry line, and 'b' in the second
line), then after validation, this is turned into ["['a', 'b']", "['a',
'b']"], so that each of the two fields consists now of the string "['a',
'b']". The bug seems to be in the validation. Am I doing something wrong,
or is this a web2py bug?
