It appears that the 'PushPage' view class needs to
implement 'IBrowserPublisher' in order to avoid default
view lookup hassles, and maybe to get the '__parent__'
set properly.
The attached patch makes the page render properly
against the current Zope3 trunk.

After adding the meta.zcml, Kevin reports:
It works great when I use the factory method and display it
through a browser view. However I'm getting an interesting
getParent not found error when trying display using the
pushpage directive:
