Sadly not EXB - we are testing Sweet for ArcGIS due to its ability to use topology rules, which are not possible in Expereince Builder : https://www.esriuk.com/en-gb/arcgis/products/sweet-for-arcgis/overview It does mean it limits some of the capabilities of Map viewer though, for example i havent found a means to view attribute tables in it.

Hi, I am new to using Sweet for ArcGIS Builder to develop an app to check on many existing features, and am looking for a way to create a shortcut which can zoom to the next feature from a layer (that has not been reviewed yet). The purpose is to make it as fast as possible to navigate to the next item that has not been checked. I have a field with an 'unchecked' attribute so would ideally skip to next feature with that on it. I would also like to be able to filter the list of features based on an attribute eg Local Authority. If one of the existing templates has this already setup i can copy how it has been done. Open to alternative ideas if this is not viable (i am aware there is no view of a table in Sweet). Any help would be appreciated! Thanks Joe

I have just been testing using ArcGIS 3.5.4 to ugrade within our team and immediatly stumbled into this issue getting the Arcade error: Spatial reference expected. on an arcade field calculation. I managed to get it to work on 3.4 but not in 3.5.4 giving the same error. The line of code it failed on was this: intersectArea += Area(intersection($feature,block), "square metres"); Would be good to know if this is fixed so we can trust an upgrade?

Hi, I am aware it is now possible to use freehand polyline drawing on Map Viewer : https://www.esri.com/arcgis-blog/products/arcgis-online/data-management/5-tips-editing-map-viewer-2025 It would be really useful if this feature was made available in FieldMaps. Ornithology team require this feature with a stylus to quickly sketch flight lines of bird on a map. Currently the ability to add verticies is not adequate for their needs. Thanks Joe

Thanks Glen - maybe its the item itself causing the issue? I will try it on a simpler version maybe. Anyway this proves the workflow works. Best regards Joe

Hi @Clubdebambos , Its a feature layer collection with multiple layers (7 or 8 i think). Its we use it as a template: Would there be a better way to generate a new hosted feature collection from a template (say from a schema?) than attempting to duplicate an existing feature collection?

Hi, I am attempting to use the copy_feature_layer_collection in a Notebook on ArcGIS Online (Python 3). Previously this worked fine (possibly when AGOL was using an older version of the python?). Now it fails. newHab = habItem.copy_feature_layer_collection(service_name = habName, layers = layer_ids_h, tables = table_ids_h, folder = folderName) The error given looks like this: --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /tmp/ipykernel_19/1373826970.py in <cell line: 0>() ---> 19 newHab = habItem.copy_feature_layer_collection(service_name = habName, layers = layer_ids_h, tables = table_ids_h, folder = folderName) /opt/conda/lib/python3.11/site-packages/arcgis/gis/__init__.py in copy_feature_layer_collection(self, service_name, layers, tables, folder, description, snippet, owner) > 13848 fs = FeatureLayerCollection(url=copied_item.url, gis=self._gis) 13849 fs_manager = fs.manager 13850 add_defs = {"layers": [], "tables": []} AttributeError: 'NoneType' object has no attribute 'url' I have tested the item and all the input parameters - all seem valid. ANy ideas why this might have happended? We used this to replace the clone_items() that also changed behavior after python updates. thanks! Joe

Hi @ValGaj - I finally (a year or more later!) got an opportunity to use your approach as python 1.8.4 is no longer available on AGOL notebook (as far as i am aware). It does work so thank you for providing this solution. To get it to work i have to clone all the layers first by cloning the initial map, then run the clone a second time on the webmap with the item_mapping setup correctly now i have the new IDs, then delete the first cloned map. This is considerably more code to achieve the same effect. I don't suppose you know of a simpler approach using this method?

This has also been tested using python in notebook on AGOL with no luck using the Contingent Values toolset

Sorry Russ - I cant share that one.

Hi Shane, Only tested on the new map viewer - if I open in classic would i lose the group layers? Many. Could be 200 layers Not on new small ones Will report back than on that. I dont want to manually recreate the map though for obvious reasons. thanks joe

Has anyone else experienced reduced performance in existing MapViewer maps since the recent February 2024 update? Maps which had a lot of layers on but overall performed fine prior to the update, are now resulting in very slow speeds to load and render.

Contingent Values can be used in FieldMaps however to get them working they need to be in feature layer that was published from ArcGIS Pro. This layer when duplicated loses its contingent values. This has been tested using 3 approaches: using a new item based on an existing layer in ArcGIS Online; making a copy in ArcGIS Online Assistant; making a copy using the clone_items() function in notebook. It would be helpful to make this possible so that a layer with a form (which are not editable in ArcGIS Pro) AND contingent values could be created without having to publish from Pro (and then re-create a complex form from scratch). It would be even better to be able to create layers from scratch with contingent values in them in ArcGIS Online without having to publish initially from Pro.

Currently to find the map projections used in ArcGIS Online is really unclear. For a feature layer it is of less importance as they can be transformed, however tile layers can only be displayed on basemap in the correct projection. Also changing a basemap changes the projection. Neither the layer or the basemap show clearly what projection they are in. It would be really beneficial to simply display this in: the item details page on a basemap in the list of basemaps so you know what you are going to get In the corner of a Map in MapViewer so you know what projection you are looking at Ideally this would be in the EPSG code and the ESRI naming.

This would also be highly beneficial to any consultancy with many projects. Categories would be a really useful way to sort out projects if there were more than a total of 200. If the 200 limit was was within each subcategory that would also work (for us anyway) : Projects:- 123 12345 Proejct 1 12346 Project 2 12347 Project 3 124 12400 Trees 12401 Fishes
