Re: [UrbanSim-Users] Problem in DPLCM results

Hakim,

I'm not sure what version of urbansim you have, but I suspect from the
error log that it is pre-August 07? I'm mentioning it because end of
July 07 we made substantial internal changes to the events_coordinator
model. It didn't change its behaviour but it extended the type of events
that can be processed. Because of these changes it is very difficult for
me now to tell you what is going wrong in your application.

If you don't want to update opus right now, you could try to update just
the events_coordinator model, since the UI hasn't change. Just replace
the urbansim/models/events_coordinator.py file with the most recent one
from the repository. The unit test probably won't work, but if you
replace them by the unit test from the old events_coordinator.py file,
it should work. (Please make copies of everything you're replacing, in
case I'm wrong.)

Let me know if this helps.
