Hi all,
There's a (minor?) bug in the Case environment as coded in four include
files (theorems.inc, theorems-ams.inc, theorems-bytype.inc and
theorems-ams-bytype.inc). The problem occurs when a case environment is
nested inside another case environment: since only one counter for cases
is declared, the nested environment screw up the counter. More
precisely, the inner environment resets the counter to zero; when LaTeX
exits back out to the enclosing case environment, the next case item
inherits the count from the inner environment.
I tried to attach a zip file containing a small example and separate
diffs to patch the four files in file format 11 (for LyX 1.6) and 34
(for LyX 2.0). Unfortunately, the mailing list bounced my message for
"prohibited content" (honestly, there were no dirty pictures in the zip
file!), and GMANE won't let me do attachments period. So I've posted
the zip to http://dl.dropbox.com/u/9417226/case_patch.zip.
If you run the sample file without the patches, you'll see that in the
output the very last case item is numbered incorrectly. The gist of the
patches is to convert Case to an enumerate environment with a customized
label (using the enumerate.sty package). The patches for version 34
(only) also improve the labels in the LyX GUI so that cases are labeled
with the correct numbers, rather than a static "Case #".
I've tested the patches against this file, but only in English. I see
that in the newer include files there's additional commands that I
assume have to do with translating the labels. It would be a good idea
if somebody tested the patch in a language other than English to make
sure I didn't screw that up.
I'll post a version on the wiki as a temporary (?) fix when I get a chance.
Cheers,
Paul
