@sumitzarkar JS API team is fixing this issue

[sumitzarkar]

@aparveen - We checked in devExt and we don't see undefiend, and now the app is working as expected.

Please let us know if any action required from our end.

• This issue is related to Reporter issue #526
• We have updated the code for CSM and CSR for this ticket. However, we see is some differences in the way how the visibility of the layers is maintained in the webmap when featureservice is added.
• In issue #526 for reporter , we got to know that - visibility is an optional property with an implicit default of true
• Whereas in this case, we are getting undefined value in the layers visibiity flag and undefined in JavaScript means false, the app is considering that the layer visibility for all the layers is false and hence we are not able to see any layers
  
• We can fix this by changing the code to check the visibility value is false or true, before that it would be helpful if we get AGOL team's input if this expected to add visibility as undefined in webmap

FYI - @aparveen

@sumitzarkar Map viewer team is saying there is not difference in the json between grouped and ungrouped layer. Is there something else going on in our app?

@aparveen @skrishn

We analyzed this in more detail and here are our findings:

• We are using ArcGIS JS API to load the details of each webmap
• For this we are using createmap method from JS API
• In response we get the itemInfo and itemData.
• So, the root cause is here, when we get the data using this method we see 'undefined' value in the visibility property of the operational layer

@sumitzarkar JS API team fixed it, the fix is in devext. Could you please see if you still getting undefined.
