To
prevent empty pages in a double-sided page environment, I have been
using
\setuppagenumbering[page=].
This does
not work as it should, however, when there is no body text but only a
continuing footnote on the last page. Then, though there are still no
empty pages, the pagenumber on the last page is the same as that on the
preceding page.
Consider
\setuppagenumbering[alternative=doublesided]
\setuppagenumbering[page=]
\starttext
\dorecurse{3}{\input
knuth}\footnote{\dorecurse{3}{\input knuth}}
%\input knuth
\stoptext
with and
without the line currently commented out.
