AttributeError: level in App/special_dtml.py using ZPublisher.Zope method

[Juan Antonio Valiño]

I created a page template (called 'form') with this content:

<h1 tal:replace="structure here/manage_page_header">Header</h1>
<p>Hello World</p>
<h1 tal:replace="structure here/manage_page_footer">Footer</h1>

Testing this page template from browser works ok, but if I use ZPublisher.Zope('/form') method within an unit test an exception is raised:

AttributeError: level

It seems that testing machinery is broken.

Changes: submitter email, importance (critical => medium)

[Jens Vagelpohl (dataflake-deactivatedaccount-deactivatedaccount)]

The old ZPublisher.Zope machinery can now be found under Zope2.debug. It has indeed been broken, but in a different way. With the fix linked below the page template described by the original poster can be executed fine using Zope2.debug.
