When a Web Feature Service (WFS) published from a hosted feature service in ArcGIS Online contains polygons and is using RD_New projection, it does not display in Map Viewer.
This issue is not reproducible in ArcGIS Online Map Viewer. If the issue occurs, contact Esri Support Services, as additional information is required for further investigation.
解决办法
Publish a feature service using the WGS84 WebMercator projection, and use this service to create the WFS.
