Instead of List<AllGameData> AllGameDataResults = (List<AllGameData>)getAllGameDataQuery.executeWithMap(args); ... Cursor newCursor = JDOCursorHelper.getCursor(AllGameDataResults);
have you tried List AllGameDataResults = getAllGameDataQuery.executeWithMap(args); ... Cursor newCursor = JDOCursorHelper.getCursor(AllGameDataResults); This is what I do. I seem to remember that by using your equivalent of List<AllGameData> the method JDOCursorHelper.getCursor(...) did not work for me. Enjoy?
