Hi,

I am learning EL functions. When I did exercise in HFSJ book, 393 page, I got following doubt.

How ${num > 3} gives false?

I was expecting error because num is not preceded by requestScope. Can anybody please explain me how it get executes?

Thanks,
Swathi.

Hi Swathi,
The variable is first searched in the pageScope all the way through to the applicatoin scope in the order page- request- session-application.
the first variable / attribute fouund with that name is used.
Hope this helps
