Thank you for your answer. I don't know why my initial post was deleted, I would have answered it sooner...
The origin of the problem was that I imported functions from a model file in a controller file. I usually do that prefixing it by if 0: from <model file> import <function or class> in order to make import errors disappear in Eclipse, so that I see the real errors ; but in this case I had forgotten this "if 0:" And as imported modules do not have access to global variables, so was it for this imported model. So, imports are dangerous :-) Le mardi 20 novembre 2012 08:09:08 UTC+1, Johann Spies a écrit : > > On 19 November 2012 15:53, Cédric Mayer <argl...@gmail.com > <javascript:>>wrote: > >> >> File >> "C:/Users/cedric/projets/LACT/eclipse/Lactw221/web2py/applications/lact/models/a34_lact_running_modes.py" >> >> <http://127.0.0.1:8000/admin/default/edit/lact/models/a34_lact_running_modes.py>, >> line 43, in on_end >> >> session.flash = T('Serie finished!
