About HFSJ, pg 311 - "Using the pageContext to find an attribute when you don't know the scope"

I remember the first time when I saw this function in someone's code and a vague explanation that it finds the attribute in the following order - page, request, session, application scope I was really curious to take a look in the API to figure what a heck does this function return - either the attribute (Object) or , who knows, the scope where the attribute resides - say PageContext.SESSION_SCOPE (you can use getAttibute(String, int) if you have this, right). It returns an Object, as pretty much expected ...

Now, when I read pg 311 from HFSJ I think that some others may like to get a better idea of what the function returns - still an Object, even 2y after my initial curiosity ...

(Don't know why, but I love to have the full description of arguments and return type for a function in general - that's what api docs are for, true ... )

In case others feel the same, for findAttribute that would be:
abstract Object findAttribute(String name) - Searches for the named attribute in page, request, session (if valid), and application scope(s) in order and returns the value associated or null.

Cheers,
Claudiu
