Using some input from a fellow GeoNet'er, and getting some more learning under my belt, I was able to get this working, today. (A nice way to start a weekend!) Here's the code I used, for the benefit of others: Geodatabase {    id: gdb_geofence    path: AppFramework.resolvedPathUrl( outputGeofencing )    onLoadStatusChanged: {       if(Enums.LoadStatusLoaded === gdb_geofence.loadStatus) {          var layer = ArcGISRuntimeEnvironment.createObject("FeatureLayer")          layer.featureTable = gdb_geofence.geodatabaseFeatureTablesByTableName["fake_brushview_polygons"]          gdbLayers.push( layer );          map.operationalLayers.append(layer);          layer.featureTable.queryFeaturesStatusChanged.connect( function() {             if (layer.featureTable.queryFeaturesStatus === Enums.TaskStatusCompleted) {                //Create array for features and collect them                var features = []                while (layer.featureTable.queryFeaturesResult.iterator.hasNext) {                   features.push( layer.featureTable.queryFeaturesResult.iterator.next() );                }                console.log( "number of features in array: ", features.length );                //Get the current map point                var newPoint = mapView.locationDisplay.location.position                //set default value for not being in a zone, before checking:                var inAZone = false;                for( var i = 0; i < features.length; i++ ) {                   var zoneGeometry = features.geometry                   var withinZone = GeometryEngine.within( newPoint, zoneGeometry );                   if( withinZone ) {                      inAZone = true                   debugMessage.text = features.attributes.attributesJson.name                   }                   if( !inAZone ) {                      debugMessage.text = "Not currently in a Zone"                   }                   console.log( i, features.attributes.attributesJson.name, " withinZone is set to ", withinZone );                }             }          });          layer.featureTable.queryFeatures( queryParameters );       }    } } ...

Right, but I'm not getting to the geometry level. I used exactly what you're describing, successfully, with the iterator, with online resources. But I can't get a successful return to my query to the Geodatabase.  In other words, I never get "Query Complete!" in my console, in my above code, even though I'm getting the layer showing up on my map.  ...

Yes, that was when I was simply trying to get GeometryEngine working with online layers. No problem doing that, but I run into difficulty when I try to get my offline data (runtime content) to the same place, where I can run GeometryEngine.within against individual features. (Polygons) The error that I referenced in my last post was really throwing me, but it sounds like it may be a known bug, and ignorable. (?)  Beyond that, I've tinkered for a while and have the following code loading the geodatabase polygon on my map, no problem.  However, when querying, I never get queryFeaturesStatus to be "Complete". I get a value of 1 from my console.  Loading to the map implies that the data is present, just not sure how to drill down to features, so that I can do my "within" call, like what worked for me, with online resources.  Perhaps there's a better way! Any thoughts? 🙂 FeatureLayer {     id: gdbFeatureLayer     // obtain the feature table from the geodatabase by name     featureTable: gdb.geodatabaseFeatureTablesByTableName["fake_brushview_polygons"]     onLoadStatusChanged: {         map.operationalLayers.append( gdbFeatureLayer );         onQueryFeaturesStatusChanged: {             console.log( "queryFeaturesStatus: ",gdbFeatureLayer.featureTable.queryFeaturesStatus );             if( gdbFeatureLayer.featureTable.queryFeaturesStatus === Enums.TaskStatusCompleted ) {                 console.log( "Query Complete!" );             }         }     }     // create the geodatabase     Geodatabase {         id: gdb         path: AppFramework.resolvedPathUrl( outputGeofencing )     } } ...

Thanks, yes, I've worked with the Feature Layer (Geodatabase) code, as well. I can load a geodatabase to the displayed map...but I've yet to get it to successfully query against it. One clue is that even the barebones Feature Layer (Geodatabase) example is getting an error in my console?: MyApp.qml:100:39: Unable to assign [undefined] to QmlFeatureTable* I've worked with this code, as well as the "Generate Geodatabase" sample; I can make features show on the map, but that's not the end game for me. I need to be able to use GeometryEngine against it (within), and can't seem to get to that extra step. Thank you for pointing out that I'm using sample code for the older runtime, that's a start! ...

Hi Aneeqa, sorry, I've been out of the office for a holiday over the last week. I'm sorry to say that I've had no luck getting this to work, so far. Most of the feedback that I've gotten simply keeps pointing me back to the same AppStudio samples, with the counsel that "it works just the same with offline content". Alas, that has not been my experience.  ... View more

Excellent, this appears to have solved my problem! Thanks so much --Ray ... View more

Great idea to try to get my SR's in sync, thanks for the response! So I did this (code below). It didn't seem to solve my problem, but the console.log seems to show that the geom1 value becomes null. Does that mean that the newPoint that I'm passing to GeometryEngine is not really a "geometry", and could be part of my problem? Console.log shows newPoint as a QDeclarativePosition if I get it from the code below, and as a QMLPoint if I get it from mapView.currentViewpointCenter.center. var newPoint = mapView.locationDisplay.positionSource.position var geom1 = GeometryEngine.project( newPoint, mySpatialReference ); var geom2 = GeometryEngine.project( zoneGeometry, mySpatialReference ); var withinZone = GeometryEngine.within( geom1, geom2 ) console.log( "withinZone", withinZone, geom1, geom2 ) Edit: adding in my spatial reference object for good measure: SpatialReference {     id: mySpatialReference     wkid: 4326 } ...

Hmmm, so perhaps you're on to something here. When I attempt to run their provided example geodatabase, I get 1 for both loadStatus and featureTable.queryFeatureStatus. If I change things to try to use my gdb, the loadStatus is 0, and the featureTable comes up as undefined. I'm not getting the geodatabase loaded properly, somehow.  ... View more

Hi, thanks Kaushik, Sorry for the delay, I got bounced around to another project for a bit! Yes, when I log the path, it does appear that it's correctly pointing to my existing .geodatabase file in the correct folder. I was hoping you might be on to something, there, that would have been something that I could have fixed! Any other thoughts? Thanks, --Ray ... View more
