Is it possible in v13.1.2 to load layers from an esri portal feature service? I managed to get map and image services working using your ArcGISServerRestLayer, but haven’t had luck with feature services. I see in the lastest release notes, https://docs.thinkgeo.com/products/desktop-maps/changelog/, it says you " Added ArcGisServerRestVectorAsyncLayer for querying and rendering ArcGIS Server REST vector feature services."
Does that mean the feature doesn’t exist in earlier versions?
