Arcade Attribute Rule and WKT Values

Mary

I am writing an attribute rule against Utility Network Datasets to update the Z value on point features based on the features lifecycle status to be fired on update and create. I have several data sets where the first code snippet is working as they have “regular” coordinate systems with wkid values. I have one dataset that is a custom coordinate system I have been attempting to extract the wkt value from the point feature to construct the new geometry. However, the second code snippet where I am doing this is causing Pro to crash when opening the attributes pane of this data set.

Any thoughts on the different behavior between WKT and WKID references? 

 

Side Note: if I disable the WKT attribute rule I do not see the crashing behavior.

WKID Z Value Update no issues:

1. var geom_text = Text(Geometry($feature));
2. var geom = Dictionary(geom_text);
3. var xGeo = geom.x
4. var yGeo = geom.y
5. var spatialRef = geom.spatialReference
6. var wkidVal = spatialRef.wkid
7. var zGeoProposed = 1
8. var zGeoOther = 0
9. if($feature.LIFECYCLESTATUS != 1){
10. var newGeo = Point({"x": xGeo, "y": yGeo, "z":zGeoOther, spatialReference: {wkid: wkidVal}})
11. }
12. else{
13. var newGeo = Point({"x": xGeo, "y": yGeo, "z": zGeoProposed, spatialReference: {wkid: wkidVal}})
14. }
15. return newGeo;
16.  

 

WKT Z Value Update Crashes Pro

 

1. var geom_text = Text(Geometry($feature));
2. var geom = Dictionary(geom_text);
3. var xGeo = geom.x
4. var yGeo = geom.y
5. var spatialRef = geom.spatialReference
6. var wktVal = spatialRef.wkt
7. var wkidVal = null
8.  
9. var zGeoProposed = 1
10. var zGeoOther = 0
11.  
12. if($feature.LIFECYCLESTATUS != 1){
13. var newGeo = Point({"x": xGeo, "y": yGeo, "z":zGeoOther, spatialReference: {wkt: wktVal }})
14. }
15. else{
16. var newGeo = Point({"x": xGeo, "y": yGeo, "z": zGeoProposed, spatialReference: {wkt: wktVal }})
17. }
18. return newGeo;

To post formatted code:

 

 

You can massively simplify your rule. It should work with a regular coordinate system. I didn't test it with a custom system, but maybe it works there, too.

var geom = Geometry($feature)
var z = IIf($feature.LIFECYCLESTATUS == 1, 1, 0)
return Point({"x": geom.x, "y": geom.y, "z": z, "spatialReference": geom.spatialReference})
