Buggy source:

  }

Fixed version (ground truth):

  }

      for (int x=0; x < fetchedFaculties.size(); x++) {
        if (selectedFaculties.get(j).equals(fetchedFaculties.get(x))) {
          Cursor cursor=surveyManager.getFacultyID(selectedFaculties.get(j));
          if (cursor.moveToFirst()) {
            selectedFacIds.add(cursor.getString(cursor.getColumnIndex("String_Node_Str")));
          }
        }
      }
    }
  }
 else {
    Cursor c=surveyManager.getAllFaculties();
    if (c.moveToFirst()) {
      do {
        selectedFacIds.add(c.getString(c.getColumnIndex("String_Node_Str")));
      }
 while (c.moveToNext());
    }
  }
