Mario Ivankovits updated MYFACES-516:
-------------------------------------
Attachment: RedirectTracker.java
> Capture and restore saveState Beans and messages when using redirect
> navigation rule
> ------------------------------------------------------------------------------------
>
> Key: MYFACES-516
> URL: http://issues.apache.org/jira/browse/MYFACES-516
> Project: MyFaces
> Type: Improvement
> Components: Implementation
> Versions: Nightly Build
> Reporter: 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.
