#application['foo'] or #application.foo ServletContext attributes 'foo'
#attr['foo'] or #attr.foo Access to PageContext if available, otherwise
searches request/session/application respectively
If I have stored the ArrayList in the ServletContext, Why it only works with
attr?
I am confused.

Try #attr.types
When you say sometimes, do you mean each time you load the page it works
sometimes and if you reload sometimes it works, or it never works?
Also, an ArrayList is a container so you don't need to initialize its size.
I don't think you are using the capacity parameter in the constructor the way
you think you are. Just types = new ArrayList() works fine.
