Yes, we would like to see full Spring View technology support for the 
Portlet API and this includes the taglibs.  Did you make 
PortletApplicationContext a subclass of WebApplicationContext?

ThemeResolver is missing since it is expected that the Portal will 
handle these things.  Perhaps the bridge View Servlet could provide a 
mock implementation to satisify the tablibs?

I think that is still an open question at this point.  We seem to have 
the Views working reasonably well...so I am still hopeful for the tablibs.
