Hi, Hans:
bug report :
here is the test file. (old version of mkiv produce right result.
current mkii result is also right)
It is a bug introduced in this/last month.
The code is a stripped down version of
http://wiki.contextgarden.net/Horizontal_Table_of_Contents (altough it
doesn't show toc horizontally)
\newcount\chapcounter \chapcounter=0
\def\tocchap#1#2#3{\advance\chapcounter by 1 #1 #2%
       \placelist[section][criterium=chapter,number=\chapcounter]}
\starttext
\placelist[chapter][alternative=command,command=\tocchap]
\chapter{hello} \section{hello} \section{hello}
\chapter{good} \section{good} \section{good}
\chapter{bad} \section{bad} \section{bad}
\stoptext
add \number in front of \listparameter\c!number in strc-lst.mkiv or just 
in front of your \chapcounter

\number\listparameter\c!number

(info passed to lua has to be expanded)

actually, there is in mkii:

\starttext

\placelist[chapter][after={\placelist[section][criterium=local]}]

\chapter{hello} \section{hello} \section{hello}
\chapter{good} \section{good} \section{good}
\chapter{bad} \section{bad} \section{bad}

\stoptext

but that does not yet work in mkiv
...
...
feature request:
btw, Hans, context should give an option to iterate through all the
chapters/sections to do something tricky.
using \chaptercounter is a really bad idea (the materials should
follow strict rules, like cannot jump from chap 1 to chap 3).
I think with mkiv it is able to achieve that.
sure, but that's for later; the mkiv structure code has much more 
possibilities but first i want to have the standard features complete 
and debugged
...
...
question:
I want to show toc before each chapter, and the toc only shows the
following chapter name in red.
How can I do that?
e.g. show the following before chapter 3
% A Page
Chap1
sec 1 sec 2 sec 3
Chap2
sec 1 sec 2 sec 3
Chap 3  %in red
sec 1 sec 2 sec 3 %in Red
Chap4
sec 1 sec 2 sec 3
% Next Page
Chapter 3 % title
a lot of materials
