Hello,

please look at the following minimal example:

----
\definehead[chapterMiddle][chapter]
\setuphead[chapterMiddle][align=middle]

\definehead[sectionMiddle][section] % Try to comment this line!

\definecombinedlist[content][part,chapter,chapterMiddle]
\setupcombinedlist[content][alternative=c]

\setuplist
   [chapter,chapterMiddle]
   [alternative=b,before=\blank,after=\blank,style=bold]

% Commands

\def\startTitlePage{
   \bgroup
     \let\chapter=\chapterMiddle
}

\def\stopTitlePage{%
   \egroup
   \page
}

%%%

\starttext
   \placecontent % = TOC
   \page

   \chapter{Cha1}

   \startTitlePage
     \chapter{Cha2}
   \stopTitlePage
\stoptext
----

Its goal is to define \(start/stop)TitlePage command in which heads will be centred (although they are not mid-aligned by default).

(I don't know if my approach is the best - I'm using \chapterMiddle instead of \chapter for this, which is defined as mid-aligned).

A \chapterMiddle is derrived from \chapter and has middle alignment.

I would need to do a similar thing with \sectionMiddle.

The problem is that when I derive a next style - "\definehead[sectionMiddle][section]" (try to comment the proper line), look of the TOC changes (?!) - some extra space before "Cha2" appears; see both test21.pdf and test22.pdf.

So how to keep the same look of the TOC?

And - would you recommend any better solution how to define \(start/stop)command which would force heads to be mid-aligned?

(All compiled with the latest beta, WinXP.)

Best regards,

Lukas
