Labels display but Symbology doesn't

DarleneRouleau — Sun, 12 Dec 2021 16:20:24 GMT

I am trying to add and view a single feature layer from our service with the following code:

_viewModel.AddLayerFromUrl(
 "http://orbittest.miner.com:6080/arcgis/rest/services/GRU_ElectricDistribution/MapServer/1", "Support Structure");

_viewModel.AddLayerFromUrl(
 "http://orbittest.miner.com:6080/arcgis/rest/services/GRU_ElectricDistribution/MapServer/15", "Lines");

public void AddLayerFromUrl(string layerUrl, string name)
 {
 var layer = new FeatureLayer(new Uri(layerUrl))
 {
 Id = name,
 Name = name,
 IsVisible = true,
 ScaleSymbols = false
 };
 Map.OperationalLayers.Add(layer);
 }

The "Lines" layer displays fine in the map. The "Support Structure" labels appear, but the actual symbols / graphics do not. I have tried with ScaleSymbols set to true and false. I am using 100.5. I have reproduced this in the Sample App WPF provided by Esri.

See attached screenshot.

I also attached the json for the troublesome layer. Note that there are multiple layers on this service that demonstrate this behavior. I also attached the .json for Anchor Guy which is a simple layer that reproduces the problem.

Hi Dariene,

Could you please try to use ServiceFeaturetable.UseAdvancedSymbology property and set to "false". I have seen few issues have been reported and adding that property makes symbology appears.

https://developers.arcgis.com/net/latest/wpf/api-reference/html/P_Esri_ArcGISRuntime_Data_ArcGISFeatureTable_UseAdvancedSymbology.htm

By default this property is true and this is applicable if you use only ArcGIS Pro Symbol.

Hope that helps. Thanks

Thanks! That fixed our specific issue.

However, how do I know, as a client app developer with my app distributed to various organizations if this should be set to true or false? For example, organization A does use ArcGIS Pro Symbology and organization B does not use ArcGIS Pro Symbology - if I hardcode this value to false then what happens to organization A?

HI Darlene,

Just so you know, this is just a workaround and we are aware of this issue. The development team is looking at this. The issue may be related with recent Windows update, but not sure at this moment. I will keep you posted to this thread what I find. Thanks

Is there a bug number I should follow to know the final resolution?

Thanks!

Hi Darlene,

I am still working on this with other resources and definitely let you know as soon as I have any update. Thank you

Be aware that some of our clients have started seeing the same issue. We'll likely ship this workaround to them as a temporary hot-fix. But, we'll be very interested in the version of Runtime that has the full fix.

Thanks for pointing that out. Unfortunately, we also see the behavior in iOS when using the Xamarin.Forms Runtime. Any thoughts for our next steps there? We've put in place the workaround, but don't know when we can remove it.

Jeremy,

We're working closely with Microsoft to resolve this issue.

The current recommended workaround documented in the other thread is to remove the listed Windows Updates (KBs) from Windows servers that host services consumed by Runtime applications or Windows desktops where ArcMap is used to generate Runtime Content.

Regards

Mike

Right, but Xamarin.Forms Runtime wouldn't involve the Windows OS when the iOS app is running. And, the app is built on a Mac. I want to be sure this bit of evidence makes it into your case. It appears to us that something more is going on here that doesn't just involve Windows or a KB that was installed there. Does the dev teams at esri have a theory for the symptoms we are seeing in iOS?

Hi Jeremy,

The underlying issue is actually on the server-side when responding to the client API requests or on the desktop when creating Runtime Content - in both cases the CIM JSON symbol generation is failing which results in a valid symbol definition (color, size, etc) but no symbol geometry to render. Setting UseAdvancedSymbology to false on the ServiceFeatureTable bypasses he server-side symbol generation/vectorization.

I believe that explains what you're seeing on iOS?

Cheers

Mike
