Hi, so deployment day is here and we found that ChangeDetector doesn't output through updated port.
Yay! (not really :-))
The workspace we're using is matching on one attribute and checking for changes in another, but even though there are changes ChangeDetector only outputs one insert and one delete - no update.
FME 2019.0 (and 2019.2)
Attaching workspace that doesnt output through updated-port, but only inserted and deleted.
