Delete last feature from a feature service with explicit save

Try to delete the last feature in a feature map service, then pan map.. you will find the feature appear again

To reproduce the case, please :

-open http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#EditToolsExplicitSave

-make sure that used feature service has only one feature
[query: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/2/query]

-select this feature , then click delete selected

-pan map

----> you can see the deleted feature appeared on map !

when we save, the feature become deleted.. but the issue is user can see deleted feature in feature service until he save which is confusing

thanks

yes ...

and in the mentioned sample they use DisableClientCaching

<esri:FeatureLayer ID="ThreatAreas"
                               Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/2"
                               AutoSave="False"
                               Mode="OnDemand"
                               ValidateEdits="True"
                               DisableClientCaching="True" />

this issue happens only while deleting last feature in a feature layer
