Description Trejkaz (pen name) 2006-05-09 05:41:56 UTC
There may be some issue with opening the ListLevel structures.  Unfortunately we
can't give you a test document for this one.  Needless to say it eliminates the
ability to read any text from the document.  It would be good if at the very
least, the things which are valid would still be read out.

Comment 3 Nick Burch 2011-02-25 17:01:16 UTC
Does this problem still remain with a recent svn nightly build / poi 3.8 beta 1 (when released shortly...)?
Comment 4 Trejkaz (pen name) 2011-04-05 00:50:33 UTC
Let's assume that it is.  We don't have a copy of a file which exhibits the issue and I can't get any sample data from the source either.
Comment 5 Maxim Valyanskiy 2011-04-11 09:13:38 UTC
I still have document that raises the same exception. Unfortunatelly, it has clear statement about restricted distribution and I can't attach it to bug report.
Comment 6 Trejkaz (pen name) 2011-04-12 06:22:20 UTC
Fair enough.  Reopening, as I'm sure it will affect us eventually too.
Comment 7 Vladimir Pevunov 2011-06-02 14:15:16 UTC
I have document which raises the same exception. This document available at <a href="http://easyimpress.com/files/english.doc"/>
Comment 8 Yegor Kozlov 2011-06-24 08:11:04 UTC
Confirmed that we still have the problem in trunk (as of r1138799).
