Mario Ivankovits resolved TOMAHAWK-503.
---------------------------------------
Fix Version/s: 1.1.5-SNAPSHOT
Resolution: Fixed
Hi!
I added a policy configuration to customize the data being saved between
redirects
New context configuration parameters:
org.apache.myfaces.redirectTracker.MAX_REDIRECTS - Default: 20
Number of redirects to track - required to allow the back-button to work.
org.apache.myfaces.redirectTracker.POLICY - Default:
org.apache.myfaces.custom.redirectTracker.policy.NoopRedirectTrackPolicy
The policy used to describe which data to save between requests. This can be
any FQN to a class implementing the RedirectTrackerPolicy.
Current implementations are:
* org.apache.myfaces.custom.redirectTracker.policy.FullRedirectTrackPolicy
Captures request beans, local and messages
* org.apache.myfaces.custom.redirectTracker.policy.MessagesRedirectTrackPolicy
Captures FacesMessages only
* org.apache.myfaces.custom.redirectTracker.policy.NoopRedirectTrackPolicy
Captures nothing (the default for JSF backward compatiblity)
> Capture and restore saveState Beans and messages when using redirect
> navigation rule

> Project: MyFaces Tomahawk
> Issue Type: Improvement
> Affects Versions: 1.1.5-SNAPSHOT
> Reporter: Mario Ivankovits
> Assigned To: Mario Ivankovits
> Fix For: 1.1.5-SNAPSHOT
>
> Attachments: impl.diff, RedirectTracker.java, sandbox.patch,
> sandbox2.patch, 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.
