I have found several problems with the DAL on GAE, which include: validator problems with list:reference http://code.google.com/p/web2py/issues/detail?id=147
represent problem with list:reference (SQLTable will not display) http://code.google.com/p/web2py/issues/detail?id=149 and belongs is broken on GAE (and it worked in the old gql.py). http://code.google.com/p/web2py/issues/detail?id=151 Each of the tickets includes a proposed solution. I'd appreciate it if people can confirm that my fixes work in general (they solved my problems) and are appropriate. As an FYI - I am building a new application from scratch right now and am building it against 1.91.6 (the new DAL) and will be running it on GAE. As i build out my app i'll be sure to let the group know of any other issues i run across with the new DAL. In general it looks like a huge improvement. Great work Massimo and crew! Thanks so much Christian ps - i'm not sure how closely people are following the bug posts on google code, please let me know if posting a message here is just too much noise, cause i too hate noise!
