 Dear list,
 Motivated by
 https://tex.stackexchange.com/questions/406892
 I wanted to disable page breaks for parts.  This works on all pages,
 except the first page of a
 document.  Why?  MWE is below as always.  Reproducible with TL 2017 and
 latest beta.
 Cheers, Henri
 \setuphead
    [part]
    [page=no]
 \starttext
 \startpart[title=Part One]
    \startchapter[title=Chapter One]
    \stopchapter
    \startchapter[title=Chapter Two]
    \stopchapter
 \stoppart
   \startpart[title=Part Two]
    \startchapter[title=Chapter One]
    \stopchapter
    \startchapter[title=Chapter Two]
    \stopchapter
 \stoppart
 \stoptext

this relates to the fatc that there has to be some node on the page 
that registers the part information and as chapter flushes a page that 
one ends up on a page then
%  solution 1:
\setuphead
  [part]
  [page=no,
   placehead=hidden]
\setuptexttexts
  [\synchronizehead{part}]
%  solution 2:
\setuphead
  [part]
  [page=no,
   placehead=hidden]
\appendtoks
   \synchronizehead{part}%
\to \everybeforepagebody
%  solution 3 (new in beta):
\setuphead
  [part]
  [placehead=section]
This will delay the flush till the next section head gets place. It's 
still not 100% predictable but it might work out ok in most cases.
Another option, that I posted on Tex.se is:
\setuphead[chapter][continue=no]
So that the page is not flushed by \startchapter immediate after a 
\startpart.

there is still a (potentially) interfering node then (which can then be 
seen from the chapter line starting lower)
