how to set spatialReference in 4.0

LoriMcCormack1

I need to have the same spatial reference between the MapView and my feature layer because I am performing a queryTask and then using the popup to zoom to the feature.  The query result feature is in State Plane, and the Map and MapView are in Web Mercator because I am using an esri basemap.  The zoom to in the popup doesn't work, and the popup won't display on the queried feature.

1.  I assumed  the search results would be projected to the map.spatialReference because I set up the outSpatialReference.  But my result features were still in State Plane

2.  Next, I tried to set the initialViewProperties to State Plane in the map.  I get an error saying the wkid is null or undefined

3.  Then, I tried to set the spatialReference in the MapView.  I get an error saying the wkid is null or undefined

4.  Finally, I tried to project my search results on the fly from State Plane to Web Mercator.  I get no errors, but the feature is still in State Plane from what I can tell by selecting a point from the path in my polyline and showing the x,y

values when I display the popup.

Here is my require statement:

The Map doesn't have a spatialReference in 4.0, but the View does.

MapView | API Reference | ArcGIS API for JavaScript 4.0

So you can do something like

view.then(function() {
  query.outSpatialReference = view.spatialReference;
  // continue rest of code
});
