def _update_object_map(self, obj_map):
obj_map['<STR_LIT>'] = self.get_droppables()<EOL>obj_map['<STR_LIT>'] = self.get_targets()<EOL>obj_map['<STR_LIT>'] = self.get_zones()<EOL>
unclear if it's better to use this method or get_object_map
        My main consideration is that MultiLanguageQuestionRecord already
        overrides get_object_map
