How are you getting into the listener of page A? Usually a listener
method gets called in response to a user submission e.g.
Page Zed is up.
User pushes button/link.
ListenerZed fires.
You push parameters into page A.
Page A renders.
User pushes button/link.
ListenerA fires. ***
At the point marked with an asterix, Page A isn't the same page A
that you pushed parameters into. It's a fresh instanace of page A, all nice
and shiny from the page pool. If you want a parameter that you set during
render to be available in subsequent listener methods, you have to declare
the parameter persistent.
