Sorry guys, I figured it out. I was missing some lines of code from the
toscawidgets tutorial. Specifically the entries in config/app_config.py,
specifically:
from tw2.core.middleware import ControllersApp as TW2ControllersApp
and
base_config.custom_tw2_config['controllers'] =
TW2ControllersApp()base_config.custom_tw2_config['controller_prefix'] =
'/tw2_controllers/'base_config.custom_tw2_config['serve_controllers'] = True
Thing is, I can't figure out why I didn't get any kind of error, or stack
trace, or any message of any kind. Nothing to indicate what might be wrong,
except the list was devoid of rows. Had column headers though :)
A secondary question might be why not? What could I have done to diagnose
this, or is it just a case of 'knowing' ?
