Hello.
I need some help with this exception when using *GWT*. I've read so much
about this issue yet I still don't understand why it happens to me.
The *exception is generated when returning a List in the method on the
server-side Service Implementation* (implementation for doing an RPC call).
I'm using Comet: when I want to load data from the database, Comet calls
the client-side Service interface method for doing so.
gameService.loadArguments(game, player, new AsyncCallback<List<
ToulminDTO>>() {
@Override
public void onSuccess(List <ToulminDTO> result) {
gameman.loadArguments(result);
}
@Override
public void onFailure(Throwable caught) {
}
});
As I print a message on the onFailure method, I realize that the problem is
when the server-side Service Impl does the "return list".
I have even done DTO classes for all of the objects that Hibernate saves
(as recommended on the GWT guides) but it hasn't solved the issue. What is
even more weird is that the *exception just happens in some moments*. I'm
using this on a Game, and in some rounds I am able to load data completely
fine, yet in others the exception occurs.
Hope you can help me.
Thanks!
