Arcade Attribute Rule and WKT Values

Mary — Thu, 30 Mar 2023 19:27:24 GMT

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:

var geom_text = Text(Geometry($feature));
var geom = Dictionary(geom_text);
var xGeo = geom.x
var yGeo = geom.y
var spatialRef = geom.spatialReference
var wkidVal = spatialRef.wkid
var zGeoProposed = 1
var zGeoOther = 0
if($feature.LIFECYCLESTATUS != 1){
var newGeo = Point({"x": xGeo, "y": yGeo, "z":zGeoOther, spatialReference: {wkid: wkidVal}})
}
else{
var newGeo = Point({"x": xGeo, "y": yGeo, "z": zGeoProposed, spatialReference: {wkid: wkidVal}})
}
return newGeo;

WKT Z Value Update Crashes Pro

var geom_text = Text(Geometry($feature));
var geom = Dictionary(geom_text);
var xGeo = geom.x
var yGeo = geom.y
var spatialRef = geom.spatialReference
var wktVal = spatialRef.wkt
var wkidVal = null
var zGeoProposed = 1
var zGeoOther = 0
if($feature.LIFECYCLESTATUS != 1){
var newGeo = Point({"x": xGeo, "y": yGeo, "z":zGeoOther, spatialReference: {wkt: wktVal }})
}
else{
var newGeo = Point({"x": xGeo, "y": yGeo, "z": zGeoProposed, spatialReference: {wkt: wktVal }})
}
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})

This works great, was not aware of IIF logic in arcade (still new to Arcade). Thanks again!
