Hello,
I'm experiencing a problem related with Restlet client under GWT (returns
NULL).
Example resource interface:
public interface VOResource {
@Get
public List<VO> retrieve();
}
where:
public class VOImpl implements VO, Serializable {
public static final long serialVersionUID = 1L;
private String id = "";
private String name = "";
private Set<User> users = new HashSet<User>();
private Set<Resource> resources = new HashSet<Resource>();
//setters and getters
}
User and Resource are Serializable.
public class VOServerResource extends ServerResource implements VOResource {
@Override
public List<VO> retrieve() {
addAccessControl(getResponse());
List<VO> result= new ArrayList<VO>();
VO vo = new VOImpl("id1", "test 1");
Set<Resource> resources = new HashSet<Resource>();
resources.add(new ResourceImpl("res1","resource 1"));
Set<User> users = new HashSet<User>();
users.add(new UserImpl("user1", "User 2"));
users.add(new UserImpl("user2", "User 2"));
vo.setUsers(users); \\ (1)
vo.setResources(resources); \\ (2)
VO vo2 = new VOImpl("id2", "test 2");
vo2.setUsers(users); \\ (3)
result.add(vo);
result.add(vo2);
return result;
}
}
On GWT site I have interface proxy:
public interface VOResourceProxy extends ClientProxy {
@Get
public void retrieve(Result<List<VO>> callback);
}
client code:
VOResourceProxy vosResource = GWT.create(VOResourceProxy.class);
vosResource.getClientResource().getClientInfo().setAcceptedMediaTypes(Arrays.asList(new
Preference<MediaType>(MediaType.APPLICATION_JAVA_OBJECT_GWT)));
vosResource.retrieve(new Result<List<VO>>() {
@Override
public void onSuccess(List<VO> result) {
// here result is NULL
}
}
My problem is the following:
If I add a set of Users or Resources to the VO object on server side [(1),
(2), (3)] then client has List<VO> result = NULL,
but when I don't add a set of Users or Resources to the VO object then
client ownse a List<VO>.
For example server returns:
//OK[12,11,0,4,0,4,3,2,10,9,0,4,8,7,6,5,1,4,3,2,2,1,["java.util.ArrayList/3821976829","...VOImpl/139707113","no_vo.jpg","java.util.HashSet/1594477813","....ResourceImpl/1043766646","","res1","resource
1","id1","test 1","id2","test 2"],0,7]
Could you please point me where is the problem and how to fix it.
Regards,
Marcin Stelmach
