So I don't have to post so many (unanswered) questions any
more...

Posting ConTeXt questions is fun, so don't stop doing this.

Alright! So maybe I am also allowed to send again
one of my favorite problems from last week?
Still unanswered. Still unsolved. Very interesting!
To whom it may concern - don't hesitate to post an answer...
Thank you all,
Steffen

Sorry, but that doesn't work.
When changed the minimal example to...
\definepagebreak
    [chapter]
    [empty,header,right]
\setuphead
    [chapter]
    [page=chapter,]
\setuppagenumbering[alternative=doublesided]

\chapter {test} \dorecurse{10}{\input tufte }

\chapter {test} \dorecurse{10}{\input tufte }
\stopbodymatter
\stoptext
... we have page numbers on (empty) page number 4, 18 and 19!
Plus there are two strange empty empty pages before the TOC?!
If you want to get a doublesided tzpeset document you should add also
 \setuplayout[location=doublesided].
I am not shure, whether the following is correct!
Empty pages at the beginning:
You start the frontmatters with the \completecontent. - I could imagine
 that
 this is a consequence of the fact that the TOC starts always on a
righthand
 page. - Thus at the  moment of \startbodymatter tex is already on the
first
 page. But after identifying the \completecontents command will create
two
 page breaks in order to be able to typeset the TOC on a righthand page.
Pagenumbers on empty pages before starting a new chapter
Chapters begin on a right hand page. If the lefthand page is empty,

is
 correctly still the pagenumber. I do not know whether it is possible to
 check whether the page before a new chapter is completely empty.
Hi Willi, I hope that it can't be to difficult:
Cause the page before a new chapter is actually completely empty JUST
BECAUSE it is generated by (Con)TeX(t) - for chapters should begin on
a right page.
So I only ask for empty pages (without pagenumbers) that are
generated by (Con)TeX(t).
That's not possible in ConTeXt?

Try the following:

\definepagebreak
    [chapter]
    [yes,header,right] % yes instead of emtpy taken from the sources
page-ini.tex line 1611
\setuphead
    [chapter]
    [page=chapter]

\setuppagenumbering[alternative={doublesided,marginedge}]
\setuplayout[location=doublesided]

This worsk for me, if no \startfrontmatter and \startbodymatter and and the
\stop... equivalents are used.
If I use the \startfrontmatter cum suis then there is a numbered page after
the TOC and the last page if even and empty is also numbered. Inside the
\startbodymatter \stopbodymatter the emptypages at new chapters are empty
pages with an empty header, thus no pagenumber.

Instead o placeing \completecontents you might want to use \placecontent
which prevents the empty pages discussed before.
