Sorry, my editor was being rather funky with the line numbers and
cutting off the and part of the 8. Actual lines are 1847-1851.

Sorry about the confusion. Typing when you are half asleep doesn't
really help.
I set the Property using self.NonUpdateFields = ["someField", "anotherField"].
When I do that, the method _setNonUpdateFields is called.
In that method, the variable self._nonUpdateFields is set properly (line 1844)
Then, the next line calls self._syncWithCursors(). However, the
fields are not added to the cursor.
To check, I did the following modifications:
def _getNonUpdateFields(self):
return self._CurrentCursor.getNonUpdateFields()
def _setNonUpdateFields(self, fldList=None):
print fldList
if fldList is None:
fldList = []
self._nonUpdateFields = fldList
print self._nonUpdateFields
self._syncWithCursors()
print self._CurrentCursor.getNonUpdateFields()
Result is:
["someField", "anotherField"]
["someField", "anotherField"]
[]
So, this tells me that _syncWithCursors is not setting the
NonUpdateFields on current cursor properly. This behavior occurs when
NonUpdateFields is passed in the constructor, set in initProperties,
or set in afterInit. If I set it after the afterInit function has
run, it is fine.
Does this clear things up? Thoughts?
