I recently updated my web2py app to version 1.91.6 (along with updating GAE to version 1.4.1) and am now able to export csv files from the appadmin as I had intended.
However, now, if I try to view _any_ of the rows within the tables by way of the appadmin, I receive a "TypeError: __str__ returned non- string (type list)" message. http://pastie.textmate.org/1458977 Please let me know if there is anything I can do to help further identify and resolve this issue.
