Class PageContext

java.lang.Object
  org.jboss.seam.contexts.PageContext

All Implemented Interfaces:

Context

public class PageContext
extends Object
implements Context

The page context allows you to store state during a request that renders a page, and access that state from any postback request that originates from that page. The state is destroyed at the end of the second request. During the RENDER_RESPONSE phase, the page context instance refers to the page that is about to be rendered. Prior to the INVOKE_APPLICATION phase, it refers to the page that was the source of the request. During the INVOKE_APPLICATION phase, set() and remove() manipulate the context of the page that is about to be rendered, while get() returns values from the page that was the source of the request.
