Closest Facility Widget not working in Flex Application Builder

Hi All,

I downloaded Closest Facility Widget for Flex Viewer Application Builder and I am able to import it successfully. It works fine while using sample ESRI Network Service.

I tried embedding my Network Service into the widget but it failed. I even tried importing my custom Closest Facility widget which is working fine using Flash Builder but no success.

Below is the Error :

Input field [sh_name] was not mapped to a field in the network analysis class "Facilities". Input field [DTNAME11] was not mapped to a field in the network analysis class "Facilities". Insufficient number of valid locations in "Facilities" or "Incidents".

Where is it actually I am going wrong for my NA service for Application Builder as the same NA service works fine for my customized Flex application.

Please help.

Thanks,
