Changing definitionExpression doesn't work

MohamedHamoud

definitionExpression attribute of FeatureLayer works fine when the application is loaded, but when I click a button that changes the definitionExpression attribute of the layer, the displayed features disappear from the map but I don't see the new features based on the new definitionExpression, although the attribute is changed.

The code I am using:

	var buildingsLyr = new FeatureLayer({
	url: "myURL",
	id: "BuildingsBM",
	renderer: renderer,
	popupTemplate: {
	title: "{ID}",
	content: "{*}"
	},
	outFields: ["ID", "Use", "Z"],
	definitionExpression: "Sector = 'S1'", // show only buildings within this sector
	});

	map = new Map({
	basemap: "streets",
	layers: [buildingsLyr]
	});

	view = new SceneView({
	container: "viewDiv",
	map: map
	,
	camera: {
	position: [54, 24, 30000],
	heading: 0,
	tilt: 35
	}
	});

// on button click, change the         definitionExpression   

	on(document.getElementById("btnLocate"), "click", function (e) {
	buildingsLyr.definitionExpression = "Sector = 'S2'"
	});

Hi Mohamed.  Take a look at this fiddle: Edit fiddle - JSFiddle .  I've added buttons to increase and decrease the building elevation. I have to agree with you that the behaviour is "buggy".  I also suspect that it might have something to do with the maximum feature count provided by the REST endpoint (2000).
