After Installing TimingAndEstimation and ScrumBurnDownPlugIn Can't Update Existing Tickets

[swithin@…]

I'm running Trac 0.10.3 on Windows w/SQLite db and Python 2.3.

I installed the timingandestimationplugin-0.1.5-py2.3.egg and TracBurndown-01.04.10-py2.3.egg plug-ins, updated the environment/db.

Then I went into the Admin page and turned all check boxes for both new plug-ins.

I could view the Burndown page as well as the Billing And Estimation pages.

When I opened an existing ticket so I could enter some hours, I got the following error after hitting the Submit button. (I also tried merely adding a new comment with no changes to other fields and got the same error).

Python Traceback Traceback (most recent call last):
