Map Spinner never stops for continues updates

YamunadeviRathinasamy

All,

I have spinner for map using "update-start" and "update-end".

I have dropdown to select the map service to add on map. The spinner works fine if do not switch the dropdown till the spinner stops on map.

If I add/remove layer when map spinner visible then the spinner never stops. because the last event fired was "update-start" and there is no update-end gets fired.

This app is developed using arcgis js api 3.20 and angular2.

Thanks,

yamuna.

I had this issue, I think there is actually a bug in the JSAPI. If you remove a layer whilst it is updating then it actually breaks the "update-start" and "update-end" events, they stop firing completely. I will try and put a test case together at some point but I found with a slow drawing layer, like an image service, the issue was very prevalent.

Anyway, I had to think of a way around it and this is what I came up with: 

this.layer.setVisibility(false); // set invisible first to ensure spinner stop

this.map.removeLayer(this.layer);
