What happens with:
def afterInitAll(self):
...
dropDown.Keys = vlKeys
dropDown.Choices = vlChoices
dropDown.ValueMode = "key"
print self.getBizobj("contact")
dropDown.DataSource = "contact"
dropDown.DataField = "title_id"
print "choices", dropDown.Choices
print "keys", dropDown.Keys
After typing the above I just re-read your original post, and see that
the offending line is where you set dropDown.Value = vlKeys[0]. You
generally don't want to do that, because the Value is coming from the
bizobj and you are setting it to an arbitrary value which would get
saved to the bizobj.
However, you should be able to do that if you really want to, if the key
is present in the choices. Otherwise, you'll get the error you
originally reported. So, please still run with the above changes and
let's see what the choices and keys are.
