Select tableView row and change map location to latitude and longitude custom properties of the row

Hello, I have a table view with several places; when the user selects a place a map view change the location to the user selction. To do this I created custom properties for each row, named "latitude" and "longitude", when the user selects a row I have a "setLocation(latitude:e.rowData.latitude, longitude:e.rowData.longitude); on iPhone it works fine, but on Android it seems like it can't get the custom properties. I tried with e.source instead of e.rowData, but nothing! The crazy thing is that if I try to alert another custom variable there are no problems, but if i try even just alerting "e.source.latitude" or "e.source.longitude" the app crashes. I tried changing the custom properties to "latitudine" e "longitudine" to avoid conflicts with latitude and longitude dafault properties of map view, but nothing! Please can someone help me with this? Suggestions?
