Description

When including a Table of Contents on a page, and there is a table on the same page which includes a combined cell, I get the following Error:

<<TableOfContents: execution failed [cannot import name AS_IS] (see also the log)>>

When there are only single cells, the Table of Contents is shown as expected.

Steps to reproduce

The following code gives an error:

<<TableOfContents>>

||<-2> test ||
|| test || test ||

This code works fine:

<<TableOfContents>>

|| test || test ||
|| test || test ||

ImportError: cannot import name AS_IS

Explanation

In the sys.path variable are two locations where a "formatter" is found, one in the standard installation, one in the MoinMoin installation. These scripts/modules conflict in namespace.

There is a file /usr/lib/python2.5/formatter.py which includes a AS_IS, which htmllib depends on, but due to MoinMoin formatter which is also in the namespace, htmllib mistakenly directs to the MoinMoin formatter.

This error is described om the Python webpage: As chapter 6.2.1 from http://docs.python.org/tutorial/modules.html tells, a script should not have the same name as a standard module otherwise errors can occur.

Workaround for my installation

If I add the following lines to /home/user/lib/python/MoinMoin/formatter/init.py before line 371, it works fine:

 371 import sys
 372 if '/home/user/lib/python/MoinMoin' in sys.path:
 373 sys.path.remove('/home/user/lib/python/MoinMoin')

Solution

There was a misconfiguration in the moin.cgi file. It was mistakenly added /home/user/lib/python/MoinMoin to sys.path.
