You've given the same name to three fields ('item[]'). web2py treats that as
one field, so it puts all the values submitted in those fields into a single
list to represent the value of the field. When an error is returned, web2py
populates the form with the previously submitted values, so it is populating
each of the item[] fields with the list of values submitted. Since there are
three fields, it should actually be ['','',''] (the empty quotes would be
replaced with actual values if any items were submitted with the form).
Is the 'items[]' field a list:string field? Why does the name have '[]' at
the end of it? What does your DB model look like?
