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-core
Environment: Trinidad 2.0 branch, JSF RI 2.0.0RC2
Reporter: Martin Koci
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
