[Zope] Call PageTemplateFile class instances

[Peter Bengtsson]

This used to work in zope 2.8 but not now in zope 2.10 (actually zope
2.10.7 to be exact)

from Products.PageTemplates.PageTemplateFile import PageTemplateFile
class MyProduct(Folder):
    meta_type = "bla"
    page = PageTemplateFile('zpt/foo.pt', globals())

    def render_page(self):
         html = self.page(self.REQUEST) # ERROR!!

The error is ridiculously large so I've truncated it:


Error in test test_foo
