Display only selected records on feature table.

I followed the script to display only the selected records on the feature table after you select by geometry as it is shown at:

However, the featuretable does not filter out the unselected records.

Can you provide a repro in codepen or something? Not sure what is different in your app versus the working sample.

It seems it occurs when you don't use a point layer. Why?

I modified the sample code from esri and I have two layers. If set the point layer active (#74), upon selection by geometry the feature table shows only the selected features. However, if you set the polygon layer active (#72 the feature table still shows all records.

Ok, I think I know what's happening with the polygons. I think what is happening here, is since the sample shows using the FeatureLayerView, it only queries data that has been downloaded and visible on the map, which makes sense.

However, if a polygon (or a polyline) is smaller than a pixel, as in, you couldn't see it anyway, it won't technically be in the LayerView since it's not drawn due to quantization in the request. This doesn't happen with points, because a point can always fit in a pixel.

If you update your demo to use fLayer.queryFeatures(query) it should work, and properly filter the table.
