I am trying to update legacy map code to the latest ArcGIS version of 4.6 and noticed this warning in the console when querying a feature layer.
[esri.core.Promise] DEPRECATED: then() -- use .when(callback, errback) instead
So I tried to change then to when, but got when is not a function errors. I also tried running the sample code from the site and got the same errors.
view.whenLayerView(featureLayer).then(function(lyrView) {
lyrView.watch("updating", function(val) {
if (!val) { // wait for the layer view to finish updating
// query all the features available for drawing.
lyrView.queryFeatures().then(function(results) {
graphics = results;
var fragment = document.createDocumentFragment();
results.forEach(function(result, index) {
var attributes = result.attributes;
var name = attributes.ZIP + " (" +
attributes.PO_NAME + ")"
// Create a list zip codes in NY
var li = document.createElement("li");
li.classList.add("panel-result");
li.tabIndex = 0;
li.setAttribute("data-result-id", index);
li.textContent = name;
fragment.appendChild(li);
});
// Empty the current list
listNode.innerHTML = "";
listNode.appendChild(fragment);
});
}
});
});
I also tried setting the "esri-promise-compatibility" flag to 1 but that didn't help. Can't see anything in the docs or community forums about this. Anyone come across this before?
