different methods between portal_catalog items and folder listContents
searched items from portal_catalog have different methods from items listed through the folder
I'm referring the same item such as the todo_item in portlet_todo.
portal_catalog item(1) has getURL whereas listed item(2) has absolute_url, but not getURL.
- has Title or id whereas 2 has title_or_id. 2's Title is different from title_or_id or 1's Title.
- has CookedBody(); 1 doesn't.
