What's the purpose of this line?
You are getting the current ID Attribute and try to set it again. This does not work.
If you want to set 'sum' as ID Attribute use this function

setSpecialAttribute(Attribute attribute, String specialName)

what should be the problem with this code? Do you get an error when you are trying to compile it?
Or does it behave unexpectedly?
Best,
