Subject [jira] Commented: (TRINIDAD-1600) Trinidad2 - Dialog navigation clears View Scope
Date Thu, 29 Apr 2010 01:58:50 GMT


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,

> 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
> Solution: use new JSF 2.0 ConfigurableNavigationHandler API
