TypeError: can only concatenate list (not "NoneType") to list
If self.__nonUpdateFields == None
then
self.__setNonUpdateFields() does not change it. It will of course
produce the error.
It seems that the method should check the value (or change the value)
so that the error is not produced.

Does anyone have any thoughts about this?
I changed it in my code but I not sure this is what Dabo wants.
def getNonUpdateFields(self):
if self.__nonUpdateFields is None:
# They haven't been set yet
self.__setNonUpdateFields()
if self.__nonUpdateFields is None:
return list(set(self.nonUpdateFields))
else:
return list(set(self.nonUpdateFields +
self.__nonUpdateFields))
Of course it prevents the error
