[zope2-tracker] [Bug 1004588] Re: A valid PageTemplate fails rendering with AttributeError in zope.tal.talgenerator

[BenJ]

This is an easy fix, but cannot be mainlined due to some incredible
disparities between zope.tal, zope.tales and zope.pagetemplates for Zope
2.x installs.

In plain english, your ZopeContext has a "_engine" property that CAN be
fed into AltTALGenerator.

So replace "self.engine" with "self.engine._engine" for
insertHTMLStructure, insertXMLStructure.

Here is a patch that works on my Zope 2.11 installation:
https://gist.github.com/benjolitz/6070af860e21a8a50771

It is meant to be applied within the /opt/Zope-2.11/ directory, but
judicious use of patch -p# can help you.


I've investigated getting this into mainline, but I'm not interested in squaring the round circle of Zope packages.
