You really should not call this a portlet. A portlet is very well defined by 
JSR 168. Note that the Zope community -- specifically CMF and Plone -- have 
misused the term for a long time.

Well, of course this does not work. The ``PageTemplate`` class does not know 
magically about a context. Have a look at 
zope.app.pagetemplate.viewpagetemplatefile.ViewPageTemplateFile to see what 
is involved in making variables available.
