Evan, This update breaks my previously working code. My site master template calls a dtml component to render a simple menu. This worked with the previous release of ZPT, but now results in a Name Error for the PARENTS[] variable. What changed in the new release to cause this and how are we now supposed to call dtml-components to avoid this problem. (Output Trace, dtml-code and object call syntax below) Regards, Frank exceptions.NameError on PARENTS in "" Traceback (innermost last): File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/www/Zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/www/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/www/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/www/Zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: index_html) File /usr/local/www/Zope/lib/python/Shared/DC/Scripts/Bindings.py, line 353, in _bindAndExec (Object: index_html) File /usr/local/www/Zope/lib/python/Products/PageTemplates/ZopePageTemplate.py, line 247, in _exec (Object: index_html) File /usr/local/www/Zope/lib/python/Products/PageTemplates/PageTemplate.py, line 155, in pt_render (Object: index_html) (Info: {'container': <Folder instance at 89d5900>, 'here': <Folder instance at 89d5900>, 'modules': <Products.PageTemplates.ZopePageTemplate._SecureModuleImporter instance at 8a28640>, 'nothing': None, 'options': {'args': ()}, 'request': <h3>form</h3><table></table><h3>cookies</h3><table><tr valign="top" align="left"><th>tree-s</th><td>'eJyLjlZ3hAJXbQtb9dhYACzMBKw'</td></tr><tr valign="top" align="left"><th>chuckmIMPlang</th><td>'en'</td></tr></table><h3>other</h3> <table><tr valign="top" align="left"><th>AUTHENTICATION_PATH</th><td>''</td></tr><tr valign="top" align="left"><th>chuckmIMPlang</th><td>'en'</td></tr><tr valign="top" align="left"><th>URL3</th><td>'http://209.48.159.60:8080'</td></tr><tr valign="top" align="left"><th>URL0</th><td>'http://209.48.159.60:8080/umle/Products/inde x_html'</td></tr><tr valign="top" align="left"><th>BASE3</th><td>'http://209.48.159.60:8080/umle/Products'</t d></tr><tr valign="top" align="left"><th>URL2</th><td>'http://209.48.159.60:8080/umle'</td></tr><tr valign="top" align="left"><th>BASE1</th><td>'http://209.48.159.60:8080'</td></tr><tr valign="top" align="left"><th>traverse_subpath</th><td>[]</td></tr><tr valign="top" align="left"><th>URL1</th><td>'http://209.48.159.60:8080/umle/Products'</td

Actually, I uploaded these at 5pm today, then I had to run and catch a plane. I still haven't updated the Project wiki, but if you visit:
http://www.zope.org/Members/4am/ZPT
...you can pick up the latest. You need to download all three; PageTemplates goes in a Products directory, TAL and ZTUtils go in 'lib/python'.
There's a trio of example Page Templates (with support data) that you can try out by copying PageTemplates/examples/zpt_examples.zexp into your import directory and importing it somewhere. One of them shows off batching, another shows how to make a tree widget, and the third calls DTML from ZPT.
Cheers,
