I saw a line in tapestry documents (http://tapestry.formos.com/nightly/tapestry5/guide/ajax.html)
Inside a component, you should use Environmental, to highlight the fact that RenderSupport (like most environmental objects) is only available during rendering, not during action requests. In fact, I just want to use Environmental Service during a action requests. (i.e. a zone update) Why this is not allowed, What other methods I can do the same thing? Thanks -- Elivoa
