Hi Jeff, The ChangeDetector outputs changed features through the NEW port. The original feature is output through the DELETED port. ie a feature is not updated, just deleted and replaced.
You could follow this up with some other transformers to help clarify the position - eg use a Matcher to see if a NEW feature ID matches a DELETED feature ID, if so it must be an edit not an addition - but I think it would be an excellent idea to have a transformer that could do this in one go. I'll suggest this to the developers - but also to Dmitri who is our Custom Transformers wiz. We might be able to create a custom transformer that does what you need.
