I am working with a feature layer web service that has no ObjectID but I want to show the features in an infoTemplate whenever the user clicks on any features from the underlying Feature Layer. But only one feature is active at a time. When I convert the event layer to a FC and publish it every single point feature is active and with a click the infotemplate pops up. I need the event layer since the requirement is to have a dynamic web service that is updated daily/hourly on one of our SQL servers. What other options do I have in this case? Any help with sample code will be highly appreciated.
