We have build an automated AGOL web map publishing tool that creates web maps with non-hosted, credential-embedded FeatureLayers that all point to a single service. Each unique web maps adds the layers with a query string parameter, e.g. the webmap JSON layers definition looks like: "operationalLayers" : [{   "id" : "Event_Collector_0",   "layerType" : "ArcGISFeatureLayer",   "url" : "https://utility.arcgis.com/usrsvcs/servers/33b430edb78b4b888933dd93b63309a0/rest/services/IMT/Event_Collector/FeatureServer/0?extraParameter=foo",    "visibility" : true,   "opacity" : 1,   "mode" : 1,   "title" : "Event_Collector - Event Point",   "itemId" : "33b430edb78b4b888933dd93b63309a0",   "layerDefinition" : null }, ...] This way, all edits performed on these webmaps appear at the destination server with their unique extra query string parameter (or POST body element), in this case "extraParameter": "foo". We use a SOI on the destination server to manipulate the data based on this parameter.  This system works very well for almost all REST operations (query, applyEdits, createReplica, etc.) but Collector will not perform a syncronizeReplica operation with replicas it has created. Instead it performs an unregisterReplica and uploads a new replica, and pops up a sign in dialog that does not successfully sign in (since we've embedded credentials in the AGOL feature service, you shouldn't have to log in anyway). My best guess as to what's happening is that Collector is not recognizing replicas that do not fit a predefined url pattern, i.e. the query string is making it think the replica is invalid. If I publish the map without any query string, Collector works normally and syncs just fine. Any ideas out there? ... View more

We are seeing apps built on the ESRI JS API version 3.17-3.19 crashing in iOS browsers when several dynamic map service layers are in the map. I have built a sample here: JS Bin - Collaborative JavaScript Debugging . The app will crash when viewed on an iPad and after a few zooms and pans. We did notice that this occurs more frequently on some iPads than others. Has anyone else seen this issue? Any workarounds besides reducing the number of layers? TIA. -Dan Walton ... View more

Ever since iOS 9 dropped, we have seen a fatal error in both Safari and Chrome for the iPad. Even most of the samples located at Samples | ArcGIS API for JavaScript  exhibit this problem. All you have to do keep zooming in until the app crashes. Has anyone else seen this? Any workarounds? ESRI, any way to fix this? It's a major problem! ... View more
