Liam, I have watched the video. From what I see, you are applying updateDefinition to the feature service and not the layer. You need to go to the layer and set the topfilter on the layer using the layer updateDefinition. You cannot update topfilter in feature service updateDefinition API. ... View more

Hi Liam, Can you pl. try only the topfilter. { "viewLayerDefinition" : { "topFilter" : { "orderByFields" : "Fix_Time DESC", "groupByFields" : "Email", "topCount" : 1 } } }  Thanks  Khaled  ... View more

Hi Liam, I think you should be able to create a view with the topfilter for this service. Can you pl. provide us with the steps to create the view in our side based on this data. We can try to repro it. I think the step that should work as follows: - Create an empty view - Call add to definition and link the view to the source - Use update definition to change the topfilter. Thanks   Khaled ... View more

That looks right to me. I have recently fixed an issue related to topfilter. The fix will be available next week as part of online feature service update. So please try it again with the update. If it is the same bug I have fixed, then if you retry apply the topfilter. It will finally work. So please try it again another time and see if this is fixed. If not, please wait until next week for the fix.  ... View more

I would try to disable change tracking, sync and enable them back. You do not need to enable change tracking if all what you need to create offline and sync. You will see change tracking in the UX under (Keep track of changes to the data (add, update, delete features). Unfortunately you will have to delete all existing replicas on this service before disable sync. It is possible sync was enabled and there has been some schema changes after.

You need to use admin service updateDefinition. Ex:  https://.../ArcGIS/rest/admin/services/<myservicename>/FeatureServer/updateDefinition and then pass the json above. Pl. note the sources of the view needs to have sync enabled. Thanks Khaled   ... View more

Pl. provide me with some info and I can double check. What API you are calling, applyEdits, etc,? I see the layer has the relationship set correctly.  ... View more

Yes you need to publish SD file to bypass the default SR which is web Mercator if you are using Pro or even arcgis.com UX. The UX does not expose the targetSR param we support at publishing. So you can use the portal Publish API directly without the UX and you should be able to override the default behavior and specify any target spatial reference as a publishing param. Publishing param in portal can contain: {    "name" : "<yourname>",     "targetSR" : { "wkid" : <>"} } You can check how the UX is publishing from arcgis.com UX (fiddler, etc.). It does call the portal publishing from your data source. Thanks Khaled ... View more

Not really understand the issue. We do support publishing data into any coordinate systems. However once the data is published, you can change the coordinate system since this would requires reprojecting the existing data. Also area and length reported in the layer query is based on the data spatial reference. BTW, these are not geodetic. You can use returnGeodetics in the query API to get more accurate measurements.  Thanks Khaled ... View more

esri blog is now live. Pl. check it out: Create a hosted feature service webhook  Thanks Khaled ... View more

If I understand this correctly, it looks like you need an order by in the view definition in addition to the top filter. We are working on this enhancement for Sept. release. Once you have the order by in the view definition, you can order by the creation date DESC which should display the features ordered by the creation date (ASC or DESC). Is this what are you looking for? Khaled ... View more

Hi Josh, No we do not support group by on geometry. Not sure I understand the issue with the display you have. You should be able to get ht most recent based on your groupby and order by you are using with the topfilter. If this is not happening, we might have an issue. Khaled ... View more

Yes we did release it yesterday. Blog url: https://www.esri.com/arcgis-blog/products/arcgis-online/sharing-collaboration/how-to-create-a-hosted-feature-service-web…  Will be available tomorrow. Just enable changeTracking in your service and you should see creating a webhook in the service admin url. Thanks Khaled ... View more

Pl. note feature service webhooks is not related to webhook on the item level. Yes webhooks is only available on admin API where you register a callback url with the feature server. Feature service will call you back to notify you with any feature service changes and allow you to fetch these changes. We have add a finer webhooks interface that tracks adding/update/delete features and attachments and also any schema changes. Webhook doc will be release in June. Thanks Khaled  ... View more
