[NTG-context] footer page number on first page of section: doesn't appear

Hi, Based on our reading of http://wiki.contextgarden.net/FO_Page_Layout#First_Page we have the following MWE, which we want to put a page number in the footer on the first page only: \definetext[footerpagenumber][footer][pagenumber] \setuphead[section][header=empty,footer=footerpagenumber,number=no,align={middle,nothyphenated,verytolerant},style=ssbf] \starttext \section{My Own Section} \dorecurse{15}{ \input knuth \par } \stoptext Unfortunately, no page number shows up. If we add \setuppagenumbering[location=footer] before the \starttext, we get the page numbering we want, but it's on every page, not just the first. Is there something wrong with our setuphead? Thanks, Lars
