I think something must be different or else the ChangeDetector wouldn't pick it up.
Check that old and new datasets both have the same number of digits on the coordinates - FME will match down to the nth decimal place given the opportunity. A CoordinateRounder may help. If the point order might be different then set lenient matching to yes (you'll probably need fme2005 for that). I'm assuming of course this is geometry matching? Hope this helps.

The "unchanged" output file created contains no data, while the "added" output file and "deleted" output file contains all the data. It is obvious from viewing the old and revised files that little has changed. Would anyone know what is happening here or how exactly the change detector works? Any help would be appreciated! Thanks.
