Yes! Of course! Because there is a small bug in web2py.js in ajax() (or
in the manual) :
If middle arg ( '[ ]' ) is string, it's treated as JQuery selector
without any processing!
So ajax() call must be like:
ajax('{{=URL('default','get_options_for_dropdown2')}}', '[name="sel_1"],
[name="sel_2"]', 'dropdown2')
