I have a custom-built Player app (started from scratch using sample Player app in AppStudio) which is meant to download and load other AppStudio apps (referred to as child apps here) I've built. I built the app for iOS devices and I'm testing it on an iPad Mini 5th Gen.  I run into issues when implementing an "Upload Photo" feature into one of my child apps. Around 50% of the time, the app crashes and becomes unresponsive when opening the FileDialog. I've narrowed the issue down to the folder property of FileDialog which is pointing to Qt.platform.os == "ios" ? "file:assets-library://" : shortcuts.pictures I'm running on iOS, so it gets file:assets-library as its value. If I change this value to  StandardPaths.standardLocations(StandardPaths.PicturesLocation)[2]  this works without crashing perfectly. But I want to point the user to the Pictures directory, so this isn't useful. Also worth mentioning is that all this works perfectly as expected, in Esri's original AppStudio player app. I can upload my child app that contains "Upload Photo" functionality to AppStudio Player and it works. It's only when I upload to my custom-built app and run my child app in there that it crashes.  This is similar to the issue @Anonymous User was having in this thread:  https://community.esri.com/t5/arcgis-appstudio-questions/file-dialog-shortcuts-pictures-crashes-a-built-app-although-not/m-p/768939   Any idea why this is crashing and what I can do to fix it?

I'm working with a feature class within an Enterprise GeoDB in ArcGIS Pro. I have a field called "Unique_ID" that I want to attach an attribute rule to. Here's the rule: whenever a new feature is inserted, I want this field to calculate the maximum value from a field called "ORIG_ID" values in the same layer, add 1 to it, and update "Unique_ID" with this number.  I have a rule within Expression Builder with the following Arcade expression. This max method being used is more or less, the same example given here: Mathematical Functions | ArcGIS for Developers under Max. var competitors = FeatureSetByName($datastore,"route.to.FeatureClass"); var uuid = Number($feature.ORIG_ID); Max(competitors,uuid) + 1‍‍‍‍‍‍ The expression is validated correctly. I set the triggers to be Insert and Update and save the process. But when I try to add a new row to the attribute table or create a feature on the map, the Unique_ID field is populated with the ORIG_ID value for that row + 1. Essentially, the maximum value of the entire field is not calculated. Any ideas on how to solve this? Thanks. ... View more

Hi everyone,  I have a GeoJSON layer that I have added to my webmap. I want to be able to click on the layer features and populate a sidepanel with elements based on the feature's properties (make request to db from app with Express query, populate sidepanel with returned array). How can I access the GeoJSON layer's properties for the feature that is being clicked? I looked at hitTest(), a MapView method. But surprised to see that GeoJSON is not a supported type of layer for the method.  Does anyone have any ideas on how I could achieve this? I'm able to access the properties on the popupTemplate fine. But I need more features than what the popupTemplate is giving me. TLDR: Need to access GeoJSON properties from clicking element on map.  Thanks! ... View more

I have a .json objects array with data that I want to use in my webmap. What is the best option to add this data (<3000 points) to the map? Should I use a GraphicsLayer object inside which I'll be adding each point as a Graphic with point geometry to? Should I use a FeatureLayer? Are there any examples in the ArcGIS JS docs that someone could point me to?  As it is now, I can add point graphics individually to a Graphic object and then add to a GraphicsLayer using layer.graphics.add(newGraphic). But how can I do this on the fly as the map is receiving data from the json? Thanks in advance! ... View more

I'm trying to create a feature for my app in AppStudio 4 where if the user clicks on one of the points on the given map, the map extent and zoom will change to center the selected point. I can't figure out how to do this. Here's my code and explanations: I'm pulling the coordinates with a http request remotely. As the data gets updated, the points will update themselves. I was able to get this working fine. Inside my http request, for each data record, I use PointBuilder to create points and graphics on the map. See below: var sr = ArcGISRuntimeEnvironment.createObject("SpatialReference", { wkid: 4326 }); var pointBuilder = ArcGISRuntimeEnvironment.createObject("PointBuilder"); pointBuilder.spatialReference = sr; pointBuilder.setXY(record.long, record.lat); var geom = pointBuilder.geometry; if (geom) { var graphic = ArcGISRuntimeEnvironment.createObject("Graphic", { geometry: geom }); graphicsOverlay.graphics.append(graphic); } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ record refers to each data point I'm pulling with the http request. This works fine and I'm able to view my points on the map. But now, I want to click or tap on the point graphic and have it respond, for instance by centering the map on the selected point. Seems like pretty basic map-component interaction behavior. But I can't find much documentation on this. How can I go about doing this?  Any ideas appreciated. Thanks! ... View more
