Subject Re: Problem with Struts 2 JSON RPC using simple HTTP Post (not using DOJO)
Date Fri, 04 Dec 2009 00:28:10 GMT
It seems like one of the fields of TransportAssignmentVO is a list,
and what is coming from the JSON objects looks more like a map, can
you set a  break point on ClassCastException exceptions and tell us
what the field is? or post the setter/getters of
TransportAssignmentVO.
