Hi,

Didn't understand your question about the string and the component but you can read about size() in the reference manual

This was an old hack to pass parameters into EL. We should really update all of these to use jboss-el.

lol.... old hack... i love that

....but how does it work?

EL allows you to lookup a a value from a map key. By creating your own implmentation of map, by extending abstractmap, and doing something funky in the get method with the key.
