Hi Massimo,
I am also not convinced since I'm new to web2py and python, but It works
fine, as expected in every case I have tested with that little correction
and a format attribute like this (*nombre* is a *string*, and *precio *is a
*decimal(2,2):*
format=lambda row: row.nombre + ' - ' + str(row.precio) + '€'
Note that the correction just tries to set the code as in the case of a
format attribute over a single reference field. I mean, is there a reason
for thar str() on *list:reference* but not in the case of *reference?*
The chars I'm using are for the spanish language: {áéíóúüñ}, in addition to
the english alphabet and '€'.
Thanks again for your dedication.
