Found this http://stackoverflow.com/questions/1867861/python-dictionary-keep-keys-values-in-same-order-as-declared on stackoverflow where the most rated post redirect here : http://dev.pocoo.org/hg/sandbox/raw-file/tip/odict.py
Notice, it will download odict.py into your computer that contain a class supposing to allow preservation of initial order in a python dict... I think, it could be nice to have this class added to web2py in order to allow insert into database of unordered list:reference field input... Since this could be slow (not in case of few value I think), it could be a choice offer to the user like : list:reference sorted or list:reference unsorted... What do you think??
