Arcade Intersect to Return a Value; Click Show, Data Error in Attribute Table

Clubdebambos — Fri, 10 Sep 2021 14:31:37 GMT

Returning an attribute from a field in an Intersect operation is populating the Popup but showing up as Data Error in the attribute table when i click 'Show'. Also is there a way to not have to click Show each time and that these values will display for all features?

// access the boundaries layer var boundaries = FeatureSetByName($map,"Boundaries") // sql to filter required boundary level var sql = "level = 4"; // apply filter var boundary_subset = Filter(boundaries, sql); // Intersect the point with the boundary var point_intersect = Intersects($feature, boundary_subset); // return the name field attribute from the boundary layer return First(point_intersect).name;

To your second question: if you could enable that, then your map would be running that entire expression for every feature loaded in the table, which would likely take a long time to run, might even crash your browser. Having the "show" link helps prevent this, and I don't anticipate that changing.

To the first question: in your screenshot, is the working popup coming from the same feature as you have highlighted in the table?

Thanks for the feedback @jcarlson

Yes, the popup is coming from the same feature as highlighted in the table. I selected and centered on the feature and it intersects with the boundary layer as returned by the value in showing in the Popup.
