Dean, You need to brush up on Python sequences and slicing.
Try this: db.thetable.thefield.writable = (request.args(-2) == 'new') request.args[0] is valid Python but it returns an index out of range error if request.args is empty. request.args(0) returns None. Same with request.args(-x) You can always tell what smartgrid is up to by parsing the arg list. Length of the arg list is significant. It gets longer when working with child objects.
