Hi Jeremy-
I think I know what is going on here. Can you try switching out your onIdentifyLayerStatusChanged signal handler to this and see if it works?
onIdentifyLayerStatusChanged: {
if (identifyLayerStatus === Enums.TaskStatusCompleted) {
featureLayer.clearSelection();
for (var i = 0; i < identifyLayerResult.geoElements.length; i++) {
selectedFeatures.push(identifyLayerResult.geoElements[i]);
}
featureLayer.selectFeatures(selectedFeatures);
}
}
I think your direct assigning of `selectedFeatures = identifyLayerResult.geoElements;` is the problem. This is now assigning selectedFeatures to the list of GeoElements, but nothing is specifically holding on a reference to the GeoElements in that list, so they go out of scope and get garbage collected after a random amount of time. On Windows, for me it was between 15-20 seconds. Whenever things randomly stop working, garbage collection is a likely culprit. I ran the below code to force garbage collection, and reliably, the selectedfeatures.length is 0.
onMousePositionChanged: {
if (selectedFeatures.length > 0) {
mouse.accepted = true;
gc();
for (var i = 0; i < selectedFeatures.length; i++) {
selectedFeatures[i].geometry = mouse.mapPoint;
}
if (featureLayer.featureTable.updateFeaturesStatus !== Enums.TaskStatusInProgress) {
featureLayer.featureTable.updateFeatures(selectedFeatures);
}
} else {
console.log("no features in selectedFeatures list");
mouse.accepted = false;
}
}
If you can confirm that this matches with your findings, then please proceed with changing your code to directly store references to the Feature(s) you want. One way to do that is how I have it in the first snippet.
