When I configure the parameters in FeatureReader to resolve domains and subtypes, it seems to have done it because when I connect it to an attribute manager I can see resolved fields. However, when I finish my process and connect them to a FeatureWriter the User Attributes tab doesn't show that it's going to assign domains to the fields that have been resolved.
I'm using FME Form 2023.1.0. I've had success dealing with domains using these two transformers before I upgraded to 2023.1.
Also not sure if it's relevant, but I'm working with an ArcSDE GeoDB.
