Witam,
testuje swoje API REST'owe "napisane" za pomocą Springa.
API działa poprawnie, sprawdzałem za pomocą curl'a. Jednak mam problem z przekazaniem obiektu w GWT'owym kliencie.
Niestety technologia została narzucona dlatego taki klient, a nie inny. Starałem się robić z pomocą dokumentacji, ale albo coś przeoczyłem albo po prostu od ciągłego wpatrywania się nie widzę błędu.
