tufte book style in lyx: when increasing or decreasing a heading it changes to unnumbered

[andrew]

when increasing or decreasing a heading the heading changes to
unnumbered (with the properly increased or decreased level). the
problem occurs only in the book (tufte) document class, not in article
or so.

what is wrong?
where is the code which defines this? my lyx layout file for tufte has
the date 2009/11/15.

thank you for help! andrew

Hello, Andrew.

This sounds like something that LyX is doing, but I'm afraid I don't
know enough about LyX to be of any help there.

When you change the heading type, be sure that you're not using the
starred version of the heading (e.g., \section* instead of \section).
The starred versions suppress the numbering of the heading and also
prevent it from appearing in the table of contents.

If you provide a simple document that demonstrates the problem, I'd be
happy to take a look at it and see if I can figure out what's
happened.

The lack of section numbering is because LyX switched the heading to
section* instead of section. I'm not sure why it's done this. You'll
have to contact the LyX folks to see if they have an idea.
