[NTG-context] Forced Page Break in a Table of Content

hi, The wiki documents how to insert a page break in a table of content: http://wiki.contextgarden.net/Table_of_Contents#Forced_Page_Break However, this does not work on ConTeXt ver: 2017.07.27 16:17 MKIV beta fmt: 2017.7.28 The following minimal document does not have the page break. \definelistextra[page][before=\page]

\starttext \placecontent[criterium=all,extras={2=page}] \startsection[title={A}] \stopsection \startsection[title={B}] \stopsection \startsection[title={C}] \stopsection \stoptext

Can anyone help me have the page break in the table of content? Thanks in advance, Antoine
