Hi dk,
Reason is probably because you have not specifically included Student
in the interface of you RPC service (as either parameter or return
value), or annotated it with a typeArg specifying Student in the 1.4.x
style. That means GWT compiler does not know that Student instances
are being passed over RPC so it cannot included it in the "white list"
maintained in the <hash>.gwt.rpc files. Hence the error. This would
happen if you wrote for example:
List getStudents() {..};
instead of:
List<Student> getStudents() {..};
If that doesn't make sense post your RPC service interface definition
for further help.
regards
gregor
