I am trying to wire Google Maps widget placed on a mashup and a Dynamic Thing template using the described GetProperties service approach for ThingWorx 7.2 (https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS243895). However, the service itself does not output an infotable bindable to GoogleMaps data input to display many things as markers on Google Maps. Previously, I was solving this issue via using GetImplementingThingsWithData service and a hidden Auto-Refresh widget. But polling the server without any data change event isn't pretty. Do you have any recommendations on implementing the right solution?
