I've created a feature layer use the client side graphics.  There is a overlap with two points(identical).  How to get all of the overlap features while click the graphics?

Hi,

could you solve the problem? I am working with JavaScript 4.4 and have the same issue. With a FeatureLayer from URL clicking on overlapping features, the template shows all popUps (1 to 4... for example). Using a FeatureLayer with client side features, the popUp shows just the feature which lies on the top of all. Is it a bug?

Best Regards,

Michael

Did anyone find a solution for this issue? I found an article referring to a regression of this behavior with the 4.2 -> 4.3 api change. 

I'm on version 4.6

I've even tried the mapview.hitTest function and I confirm that the promise only returns the top most point.  Both points are in the same feature layer.

I hope there is a solution to this....
