How do you use the ViewPageTemplateFile?
As far as I can tell, <browser:page template="foo.pt" class=".FooView">
is indistinguishable from
class FooView(BrowserView):
index = ViewPageTemplateFile("foo.pt")
def __call__(self):
return self.index()
so if viewlets work in one case, they should work in the other as well.
If your ViewPageTemplateFile is not a class attribute, the descriptor
magic does not happen and it does not know what view it belongs to.
In that case this should be the correct usage:
class FooView(BrowserView):
def __call__(self):
template = ViewPageTemplateFile("foo.pt")
return template(self)
