What are you doing?, You aren't accessing the same bean, you first get
a bean using Usebean and save it in "faq" id, but you next get another
instance from the request object, exactly an array of this beans.
Then in the for loop you overwrite the faq id with the components of
the array, and use it as if it was the Bean you got with Usebean?, I
don't understand this, but I think it could be wrong.
