Hi, I was investigating a WFS cascading issue when I stepped on this two pieces of code (this code is the same in the old WFS store and the new one): https://github.com/geotools/geotools/blob/master/modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/parsers/XmlSimpleFeatureParser.java#L180-L180 https://github.com/geotools/geotools/blob/master/modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/parsers/XmlSimpleFeatureParser.java#L881-L895
So if GT is not capable to extract a feature id (FID) from a feature, the current feature and all next features are ignored. I checked WFS specification and related schemas, GML schemas and searched on GS\GT mailing list and I'm not sure I understood correctly all the behavior around features FIDs. My impression is that a feature should always be uniquely identifiable by an ID but at the same time nothing in GML seems to enforce that. GeoTools on is side seems to also assume that a feature can be always uniquely identified by an id (I may be wrong). Can someone shine a light on this ? Regarding the WFS cascading behavior, does it make sense to allow the user to select an attribute that can be used as FID ?
