Haven't myself, but some things to check:
* you have *not* named your top-level module "load_forecasting"
(same-name packages as children often cause import issues)
o that is, your package is not
load_forecasting.controllers.load_forecasting.Index_LoadForecasting
* you can import the module from "paster shell development.ini"
* your template file really is there with proper __init__'s all the
way down to it...
from what I can see, the decorator is trying to find your *template*
file and is failing on that lookup from pkg_resources().
Good luck,
Mike
