The offending line(s) aren't directly causing the traceback. The problem
appears to be that the bizobj reports that the value of contact.title_id
is 0.
Do a:
dropDown.Choices.append("---None---")
dropDown.Keys.append(0)
and you should see the traceback disappear.
You probably need to set a sensible default value for title_id in your
bizobj (one that is one of the choices presented in the list).
