Hi all I have created a service like mentioned above.. When i loading a mashup i am getting an error like "Wrapped java.lang.Exception: Unable To Convert From org.mozilla.javascript.Undefined to LOCATION" on Application log.

*Note : NEB,NWB,SEB,SWB are inputs (Location basetype)

How can i resolve this issue?

Thanks & Regards,
