ViewTag makes wrong class cast when using locale attribute
----------------------------------------------------------

                 Key: MYFACES-1394
                 URL: http://issues.apache.org/jira/browse/MYFACES-1394
             Project: MyFaces Core
          Issue Type: Bug
          Components: Portlet_Support
    Affects Versions: 1.1.5-SNAPSHOT
         Environment: Java 1.5.0.06 + JBoss Portal Server 2.2.1-SP3
            Reporter: Jan Peter Stotz
         Attachments: Stacktrace.txt

When using JSF inside a portlet the locale attribute of the view-tag can not be 
used because a ClassCastException is thrown. 
This is because ViewTag.setProperties(UIComponent component) assumes that 
getFacesContext().getExternalContext().getRequest() returns a 
javax.servlet.ServletRequest which is only correct for non-portlets. For 
portlets it returns an javax.portlet.PortletRequest which can not be casted to 
javax.servlet.ServletRequest.
