Regards, Stephan Yes, portlets that implement JSR-168 must be able to be minimized, others don't since they don't implement the specification. cf http://en.wikipedia.org/wiki/Portlet "Portlets are reusable Web components that display relevant information to portal users." this definition is simple enough that anyone can relate to it. But there's a sense of confusion that arises from inventing new words for API reasons. Namespaces are sufficient for that, I think when used as adjectives: jsr168.portlet ibm.portlet zope3.portlet zope2.portlet cpsskins.portlet cmf.portlet plone.portlet ... why invent a new word? these are just different specifications / implementation of a same thing.

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.
