Null/Empty viewId in InitParameter causes NullPointer Exception in bridge
-------------------------------------------------------------------------

                 Key: PORTLETBRIDGE-102
                 URL: https://issues.apache.org/jira/browse/PORTLETBRIDGE-102
             Project: MyFaces Portlet Bridge
          Issue Type: Bug
          Components: Impl
    Affects Versions: 2.0.0-alpha, 1.0.0-beta
            Reporter: Michael Freedman
            Assignee: Michael Freedman


The Bridge doesn't check if a default viewId passed by the portlet is not null 
or empty -- yielding a nullPointerException.  Since the GenericFacesPortlet 
acquires this default viewId by reading a portlet.xml initParameter its 
possible for a mode to be defined with an empty or null entry.  Neither the GFP 
nor the Bridge expects this/recognizes/excludes this -- instead the GFP passes 
it along to the Bridge which happily derefernces the viewId (null) and results 
in a NPE.
