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
