Solved in some extend:
The problem is that each widget is initialized with the record values on
the SQLFORM constructor if any, in the case you need to pre-populate the
form
(http://web2py.com/books/default/chapter/29/07/forms-and-validators#Pre-populating-the-form)
it work flawless for all the other fields except for 'list:string', in my
case the 'keywords' field.
I'm getting around the problem using defaults, in the controller:
def edit():
item = db.item(request.args(0))
concrete_item = db.concrete_item(item_id=item.id)
fields = []
# before adding the the fields
db.item.keywords.default = item.keywords
# ---
for f in item:
fields.append(f)
for f in concrete_item:
fields.append(f)
form = SQLFORM.factory(*fields)
# put values to form fields
for f in db.item:
form.vas[f.name] = item[f.name]
for f in db.concrete_item:
form.vas[f.name] = concrete_item[f.name]
if form.proccess().accepted:
# here call update_record, etc.
pass
return dict(form=form)
