I have a File geodatabase with field aliases that are in the correct case that I wish to preserve, however, I need the field names to be in uppercase.

I have tried to do this using the AttributeExposer, followed by a Tester:

with the values that end with _alias being passed directly to the writer while the values that fail i pass to a BulkAttributeRenamer to convert them to uppercase before passing them to the writer.

- but i don't think the aliases are being passed to the writer properly because everything ends up in uppercase.

 How can i correct this, preferably while still using the Tester transformer?
