While trying to read the field '' of an object loaded from local variable ''

Hi All,

I have a WD Java application for which the DC is migrated from 7.0 to 7.3. When I trigger an action, the application throws 'while trying to read the field 'cdate' of an object loaded from local variable 'date''. I cant see the log using NWA also. It will be very helpful if somebody helps me out since I cant even track the error.
