[reportlab-users] format not resolved

[gonandriy]

Hello!

Why I can get such error:

File "/usr/local/lib/python2.6/dist-packages/mwlib.ext-0.12.3-py2.6-
linux-i686.egg/mwlib/ext/reportlab/pdfbase/pdfdoc.py", line 1764, in
format
    if f is None: raise ValueError, "format not resolved %s" %
self.name
ValueError: format not resolved 0

What's may be wrong?
Thanks!
