Hello,
I'm annotating a method, using typeArgs, which returns a list of maps
and am getting a SerializationException that tells me
'java.util.HashMap' was not included in the sererialization policy.
(Stack trace below). I'm unsure exactly how to represent a list of
maps and have tried both
* @gwt.typeArgs <java.lang.String>
And
* @gwt.typeArgs <java.lang.String,java.lang.String>
However, neither seems to be picked up. Any ideas what's wrong?
public interface IAccessCoursesService extends RemoteService {
/**
* @gwt.typeArgs <java.lang.String,java.lang.String>
*/
List getHomeAreas();
}
public class AccessCoursesServiceImpl extends RemoteServiceServlet
implements IAccessCoursesService {
public List getHomeAreas() {
Map map;
List list = new ArrayList();
ILearningManagementSystemMembership[] lmss =
(ILearningManagementSystemMembership[])getLMSWrapper().findDomainObjects(person,
null);
for (int i = 0; i < lmss.length; i++) {
map = new HashMap();
ILearningManagementSystemMembership lms = lmss[i];
map.put(IAccessCoursesService.HOME_AREA_NAME,
lms.getLearningManagementSystem().getName());
parseHomeArea(lms.getHomeAreaXML(), map);
list.add(map);
}
return list;
}
}
