ViewSelector
"Renderable" view selections typically can have 'render-actions' execute before they are created. An example would be an ApplicationView that forwards to a view template like a JSP. "Non-renderable" view selections are things like a flow execution redirect--no render actually occurs, but only a redirect--rendering happens on the new redirect request.
