Thanks Michael, this was super helpful and got my script working. To piggyback on this, if retrieving the index name programmatically is desired, you can do it like this: import requests from arcgis.gis import GIS from arcgis.features import FeatureLayerCollection gis = GIS(portal_url, username, password) token = gis._con.token item = gis.content.get(item_id) layer_index = 0 service_definition_url = f"{item.url}/{layer_index}/?token={token}&f=json" response = requests.get(service_definition_url) service_definition = response.json() for index in service_definition["indexes"]: if index["fields"].lower() == "shape": shape_index_name = index["name"] break flc = FeatureLayerCollection.fromitem(item) update_dict = {"indexes":[{"name": shape_index_name, "fields": "Shape"}]} result = flc.layers[layer_index].manager.update_definition(update_dict) if result: print(f"\nSpatial index successfully rebuilt for {item.title} ({item.id}), Layer {layer_index}")

Thanks again, Chris. The Windows 11 devices where it's failing are not mobile devices (they are both Dell XPS notebooks). Would I need to open a support ticket to get these device types added to the bug description (or logged as a new one)?

Hi Chris, Thanks for the reply. I tested on the five devices I have available; here are the results: Windows 10 (Edge 121.0.2277.83): App works as expected! Windows 11 (Edge 120.0.2210.144): Issue persists Windows 11 (Firefox 122.0): Issue persists iPad running iOS 15.6.1 (Safari): Issue persists iPhone running iOS 17.0 (Safari): Issue persists I noticed that when I enter full screen on the one device that works, I get the "Press Esc to exit full screen" modal, but this doesn't happen on the other Windows devices.

Hi Chris, Yes, I'm using AGOL. Here is an example: Address & Parcel Viewer (arcgis.com) I see the same behavior in Edge and Firefox on Windows, as well as Safari on iOS.

Hi Aaron, this will delete a specific user's map areas. I've found the user.items() query to be lacking as well, so I always query user items with gis.content.search, like so: from arcgis.gis import GIS gis = GIS("home") username_to_search = '' user_map_areas = gis.content.search(query=f"owner:{username_to_search}", item_type='Map Area', max_items=10000 ) for area in user_map_areas: try: delete_result = area.delete() if delete_result: print(f"Map area '{area.title}' ({area.id}) deleted.") except Exception as e: print(f"! Deletion failed for map area '{area.title}' ({area.id}). Exception: {e}")

The full screen button on the map widget doesn't work to exit full screen - nothing at all happens when it's clicked while in full screen mode (doesn't exit full screen, and nothing logged to the console). Pressing Esc does nothing. Is the ExB team aware of this? The extent navigation, measure, select, basemap, and layer list buttons also do nothing while in full screen mode. @TonghuiMing

It's probably all the empty field names. Hard to say without seeing the actual CSV.

Hi, I see two issues right away: There are no features in the addFeatures payload. You must pass an array of features to be added. addFeatures does not accept a 'where' parameter. You need to query your hosted (ArcGIS Online) feature layer, then pass those features to the 'features' parameter of the addFeatures payload. If you're wanting to do this in chunks, the chunks would be best handled on the query; in other words, query 2000 records and add them, then query the next 2000 and add those, etc. If you have attachments, those will need to be handled separately. But this should move your features over in 2000-feature chunks: import requests import json source_service_url = "" destination_service_url = "" batch_size = 2000 offset = 0 while True: query_url = f"{source_service_url}/query" query_params = { "f": "json", "where": "1=1", # Change if you want to specify which features to query from source "outFields": "*", "resultOffset": offset, "resultRecordCount": batch_size, "token": agoltoken } query_response = requests.get(query_url, params=query_params) features = query_response.json().get("features") if not features: break # no more features to process add_url = f"{destination_service_url}/addFeatures" add_params = { "f": "json", "features": json.dumps(features), "token": portaltoken } add_response = requests.post(add_url, data=add_params) offset += batch_size

This should work for you, or hopefully put you on the right track. The code below will delete ALL features in your service in 2000-record chunks, unless you modify the where_clause variable to specify only certain features. Use with caution. You may also want to look at Truncate (Feature Layer)—ArcGIS REST APIs | ArcGIS Developers if you are truly trying to delete every feature. import requests feature_layer_url = "https://<your_server_url>/arcgis/rest/services/<some_feature_service>/FeatureServer/0" where_clause = "1=1" # this will grab all features, or you can replace with a different where clause. The objectid chunks will be handled later. batch_size = 2000 while True: query_url = f"{feature_layer_url}/query?where={where_clause}&returnIdsOnly=true&f=json&token={portaltoken}" query_result = requests.get(query_url).json() object_ids = query_result.get("objectIds", []) if not object_ids: break # No more features to delete for i in range(0, len(object_ids), batch_size): batch_ids = object_ids[i:i + batch_size] where_clause_with_ids = f"{where_clause} AND OBJECTID >= {min(batch_ids)} AND OBJECTID <= {max(batch_ids)}" delete_params = { 'where': where_clause_with_ids, 'f': 'json', 'rollbackOnFailure': True, 'token': portaltoken } response = requests.post(f"{feature_layer_url}/deleteFeatures", data=delete_params) delete_result = response.json() if 'deleteResults' in delete_result: deleted_features = delete_result['deleteResults'] for feature in deleted_features: if 'success' in feature and feature['success']: print(f"Deleted feature with objectId {feature['objectId']}") else: print(f"Failed to delete feature with objectId {feature['objectId']}") else: print(f"Error deleting features. Response: {delete_result}")

Hi Adam, It's not clear to me what element type you're working with, but perhaps this will put you on the right track. I wrote an expression that checks your two conditions, then changes the background color of a list item if both conditions are met, and also adds the text ALERT to the item. var DateTieIn = $datapoint.DateTieIn; var GISStatus = $datapoint.GISStatus; var moreThanTenDays; var alert; var alertText; IIf(DateDiff(NOW(), DateTieIn, "days") > 10, moreThanTenDays = true, moreThanTenDays = false ); IIf(moreThanTenDays == true && GISStatus != "Mapped in GIS", alert = true, alert = false ); IIf(alert, alertText = 'ALERT', alertText = null); return { textColor: '', backgroundColor: IIf(alert, 'red', 'white'), separatorColor:'', selectionColor: '', selectionTextColor: '', attributes: {alertText:alertText} } The result looks like this: Here's how the Line item template is configured:

We need to be able to select a large number of records in the Table widget (for example, after applying a filter in the Table widget, we want to select all the features that meet the filter). Currently, holding down Shift while clicking records does the same thing as holding down CTRL, meaning each record must be clicked individually, which isn't practical for hundreds of records. We would like to be able to select a record, scroll down, hold Shift, and click another record, selecting all records between the clicked rows, just like ArcGIS Pro, Excel, and the Attribute Table widget in WAB.

Thanks Doug. I think the filters might be our best option here. From my testing, the only way to make the views in the offline area match the web map again is to update the map area, then have the user delete the map area from their device and re-download -- not ideal for workers in the field. I appreciate your help.

I have a web map with five hosted feature layer views (all pulling from the same parent) representing different inspection statuses (pending, in progress, completed, etc.). This map is being used for offline field collection using map areas defined on the web map item. When edits are made to the inspection status and the offline area is synced on the device, the hosted feature layer view filter apparently fails to apply to exclude the previous value. For example, when changing from "pending" to "completed", points show for both statuses: Before edit, we have one feature at this location with status "pending": After changing the status to "completed" and syncing the offline map area, we now have two points at the same location, showing both statuses: Any ideas how to resolve?

‎12-01-2023

Oh shoot, I deleted my response because it looked like you had solved your issue already by the time I posted it. So here it is again for posterity: var unitNumber = $feature.UNIT_NUMBER var hasValue IIF(IsEmpty(unitNumber), hasValue="N", hasValue="Y") return hasValue

In an AGOL notebook, you can just use gis=GIS("home"). In fact, that might be preferred over hardcoded credentials. This way, credentials aren't exposed, and if you change your password, you don't have to edit your Notebook code. That said, I think the bug that is discussed in the link I sent is probably not relevant in an AGOL Notebook anyway. Seems to be limited to Pro 3.1/Python API 2.2.0.3. But I could be wrong about that.
