Request Cycle Attributes Cleared

[Eric Everman <ev...@precedadesign.com>]

Hi-

I'm trying to allow to components to talk to each other using requestcycle 
attributes.  Component A has a DirectLink and is not in a form.  When A's 
link is clicked and its listener activated, the listener places a value in 
the request cycle using setAttribute().  The page is not changed.  As the 
same page renders, Component B looks for the attribute but it is not there.

Looking at the framework code, I see that the attributes are cleared before 
the page renders.  This is very counter-intuitive.  How can I allow these 
component to communicate? (Using alpha 5)

Thanks in advance,

You can use ordinary HttpServletRequest attributes for your purpose.  The
reason IRequestCycle has attributes is to support clearing of them after the
render (or rewind).
