[web2py] unable to parse csv file 'NoneType' object is unsubscriptable with list:reference type field

[Richard Vézina]

Hello,

Is it possible the table csv import method be broken?

When I use list:reference type field I can't import back a exported CSV
with the appadmin.

I don't understand where the None value could come from...

When I try to implement my own csv import function base on this thread :
https://groups.google.com/forum/?fromgroups#!topic/web2py/lDi0lLK_Wm0

That work fine, until I try to import data with list:reference type field
(|id| or |id|id|, etc.)

I get this traceback :

for v in bar_decode_string(value)]
TypeError: 'NoneType' object is unsubscriptable

            elif field.type.startswith('list:string'):
                value = bar_decode_string(value)
            elif field.type.startswith(list_reference_s):
                ref_table = field.type[len(list_reference_s):].strip()
                value = [id_map[ref_table][int(v)] \
                             for v in bar_decode_string(value)]

            elif field.type.startswith('list:'):
                value = bar_decode_integer(value)
            elif id_map and field.type.startswith('reference'):
                try:

Variablesglobal bar_decode_string<function bar_decode_string>value'|35|1|'v
'35'

What is exactly id_map?

I think problem is coming from there...

Thanks
