solved in tomahawk-sandbox (RedirectTracker) except for the param thing

> Key: MYFACES-516
> URL: http://issues.apache.org/jira/browse/MYFACES-516
> Project: MyFaces Core
> Type: Improvement
> Components: General
> Versions: 1.1.1
> Reporter: Mario Ivankovits
> Assignee: Mario Ivankovits
> Attachments: RedirectTracker.java, impl.diff, tom.diff

> Ok, this is a try to get what is described in the summary.
> The heart of this patch is the RedirectTracker.
> How it works:
> *) In NavigationHandlerImpl when it comes to the redirect the RedirectTracker will capture all required (save-state beans/messages) data. The tracker appends a special parameter (_rtid=) to the redirect url so the saved state can be looked up in an map.
> *) In LifeCycleImpl in restoreView the RedirectTracker will check for the special parameter and lookup the map using its value. If an entry was found the data will be restored.
> *) In UISaveState every bean rematerialized in restoreState will put it in a request-scoped map
> Known limitations:
> *) need to make the number of tracked redirects configureable (back-button) currently its hard-coded to 20
> *) some, as I didnt tested it very well
> I added this patch as a base to discuss what could be made better, though the goal is to add this functionality to myFaces.
> I hope some else jump in and we get a vital discussion about this topic.
