Thanks for your prompt response. Yes looks like a valid solution. Now report is giving exception that lat and long field can not be empty for markers. I am sure I am not setting parameter values with lat/long from dataset at right time. Please help assigning values to these parameters?

On Jasper Report, I have a map component in detail band. I am showing an object on map as per the lat/long returned from database. I am restricted to show all markers on single map thats why I have to put this component in detail band. Map component is iterating itself and showing multiple maps each carrying single marker indicating the object's location. For first few records, rendered maps are fine showing single marker but as I scroll down the report, maps start showing multiple markers. I am not getting from where it is picking the data as subdataset is returning single row only. I tried resetting the marker data but it didnt help too. I am using Jasper's Product Version: 5.6.0, Build: 20140608_2355. Please help.
