Martin Marinschek commented on TRINIDAD-1600:
---------------------------------------------
Hi Martin, Max,
in cs-JSF, independent of your discussion, we followed the original approach
suggested by Max with our dialog handling - I am not entirely sure that the
view-map should be cleared when setViewRoot is set. I believe that this is
somewhat too much of hidden behaviour for this method. Should we take this up
with the EG?
best regards,
Martin
> Trinidad2 - Dialog navigation clears View Scope

> Key: TRINIDAD-1600
> URL: https://issues.apache.org/jira/browse/TRINIDAD-1600
> Project: MyFaces Trinidad
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha
> Environment: Trinidad 2.0 branch, JSF RI 2.0.0RC2
> Reporter: Martin Koci
> Assignee: Max Starets
> Fix For: 2.0.0.3-core

> Attachments: patch.txt, patch2.txt, patch3.diff

>
> JSF 2.0 introduces new scope "View Scope" implemented with a Map
> UIViewRoot.viewMap. Spec also says that call FacesConfig.setViewRoot() clears
> that Map.
> Problem: Trinidad NavigationHandler uses method handleNavigation for
> detection if a dialog navigation will be performed - however that method
> creates new UIViewRoot and sets it to FacesContext -> clears view scope. If
> user places managed bean into view scope and starts a dialog: navigation on
> that view, bean is removed and new instance of the bean is created after
> dialog return.
> Solution: use new JSF 2.0 ConfigurableNavigationHandler API
